+[![Build Status](https://api.travis-ci.com/alexcrichton/proc-macro2.svg?branch=master)](https://travis-ci.com/alexcrichton/proc-macro2)
+[![Latest Version](https://img.shields.io/crates/v/proc-macro2.svg)](https://crates.io/crates/proc-macro2)
+[![Rust Documentation](https://img.shields.io/badge/api-rustdoc-blue.svg)](https://docs.rs/proc-macro2)
+
+A wrapper around the procedural macro API of the compiler's `proc_macro` crate.
+This library serves three purposes:
+
+- **Bring proc-macro-like functionality to other contexts like build.rs and
+ main.rs.** Types from `proc_macro` are entirely specific to procedural macros
+ and cannot ever exist in code outside of a procedural macro. Meanwhile
+ `proc_macro2` types may exist anywhere including non-macro code. By developing
+ foundational libraries like [syn] and [quote] against `proc_macro2` rather
+ than `proc_macro`, the procedural macro ecosystem becomes easily applicable to
+ many other use cases and we avoid reimplementing non-macro equivalents of
+ those libraries.
+
+- **Make procedural macros unit testable.** As a consequence of being specific
+ to procedural macros, nothing that uses `proc_macro` can be executed from a
+ unit test. In order for helper libraries or components of a macro to be
+ testable in isolation, they must be implemented using `proc_macro2`.
+
+- **Provide the latest and greatest APIs across all compiler versions.**
+ Procedural macros were first introduced to Rust in 1.15.0 with an extremely
+ minimal interface. Since then, many improvements have landed to make macros
+ more flexible and easier to write. This library tracks the procedural macro
+ API of the most recent stable compiler but employs a polyfill to provide that
+ API consistently across any compiler since 1.15.0.
+
+[syn]: https://github.com/dtolnay/syn
+[quote]: https://github.com/dtolnay/quote
+
+## Usage
+
+```toml
+[dependencies]
+proc-macro2 = "0.4"
+```
+
+The skeleton of a typical procedural macro typically looks like this:
+
+```rust
+extern crate proc_macro;
+
+#[proc_macro_derive(MyDerive)]
+pub fn my_derive(input: proc_macro::TokenStream) -> proc_macro::TokenStream {
+ let input = proc_macro2::TokenStream::from(input);
+
+ let output: proc_macro2::TokenStream = {
+ /* transform input */
+ };
+
+ proc_macro::TokenStream::from(output)
+}
+```
+
+If parsing with [Syn], you'll use [`parse_macro_input!`] instead to propagate
+parse errors correctly back to the compiler when parsing fails.
+
+[`parse_macro_input!`]: https://docs.rs/syn/0.15/syn/macro.parse_macro_input.html
+
+## Unstable features
+
+The default feature set of proc-macro2 tracks the most recent stable compiler
+API. Functionality in `proc_macro` that is not yet stable is not exposed by
+proc-macro2 by default.
+
+To opt into the additional APIs available in the most recent nightly compiler,
+the `procmacro2_semver_exempt` config flag must be passed to rustc. As usual, we
+will polyfill those nightly-only APIs all the way back to Rust 1.15.0. As these
+are unstable APIs that track the nightly compiler, minor versions of proc-macro2
+may make breaking changes to them at any time.
+
+```
+RUSTFLAGS='--cfg procmacro2_semver_exempt' cargo build
+```
+
+Note that this must not only be done for your crate, but for any crate that

+// rustc-cfg emitted by the build script:
+//
+// "u128"
+// Include u128 and i128 constructors for proc_macro2::Literal. Enabled on
+// any compiler 1.26+.
+//
+// "use_proc_macro"
+// Link to extern crate proc_macro. Available on any compiler and any target
+// except wasm32. Requires "proc-macro" Cargo cfg to be enabled (default is
+// enabled). On wasm32 we never link to proc_macro even if "proc-macro" cfg
+// is enabled.
+//
+// "wrap_proc_macro"
+// Wrap types from libproc_macro rather than polyfilling the whole API.
+// Enabled on rustc 1.29+ as long as procmacro2_semver_exempt is not set,
+// because we can't emulate the unstable API without emulating everything
+// else. Also enabled unconditionally on nightly, in which case the
+// procmacro2_semver_exempt surface area is implemented by using the
+// nightly-only proc_macro API.
+//
+// "slow_extend"
+// Fallback when `impl Extend for TokenStream` is not available. These impls
+// were added one version later than the rest of the proc_macro token API.
+// Enabled on rustc 1.29 only.
+//
+// "nightly"
+// Enable the Span::unwrap method. This is to support proc_macro_span and
+// proc_macro_diagnostic use on the nightly channel without requiring the
+// semver exemption opt-in. Enabled when building with nightly.
+//
+// "super_unstable"
+// Implement the semver exempt API in terms of the nightly-only proc_macro
+// API. Enabled when using procmacro2_semver_exempt on a nightly compiler.
+//
+// "span_locations"
+// Provide methods Span::start and Span::end which give the line/column
+// location of a token. Enabled by procmacro2_semver_exempt or the
+// "span-locations" Cargo cfg. This is behind a cfg because tracking
+// location inside spans is a performance hit.

+//! A wrapper around the procedural macro API of the compiler's [`proc_macro`]
+//! crate. This library serves three purposes:
+//!
+//! [`proc_macro`]: https://doc.rust-lang.org/proc_macro/
+//!
+//! - **Bring proc-macro-like functionality to other contexts like build.rs and
+//! main.rs.** Types from `proc_macro` are entirely specific to procedural
+//! macros and cannot ever exist in code outside of a procedural macro.
+//! Meanwhile `proc_macro2` types may exist anywhere including non-macro code.
+//! By developing foundational libraries like [syn] and [quote] against
+//! `proc_macro2` rather than `proc_macro`, the procedural macro ecosystem
+//! becomes easily applicable to many other use cases and we avoid
+//! reimplementing non-macro equivalents of those libraries.
+//!
+//! - **Make procedural macros unit testable.** As a consequence of being
+//! specific to procedural macros, nothing that uses `proc_macro` can be
+//! executed from a unit test. In order for helper libraries or components of
+//! a macro to be testable in isolation, they must be implemented using
+//! `proc_macro2`.
+//!
+//! - **Provide the latest and greatest APIs across all compiler versions.**
+//! Procedural macros were first introduced to Rust in 1.15.0 with an
+//! extremely minimal interface. Since then, many improvements have landed to
+//! make macros more flexible and easier to write. This library tracks the
+//! procedural macro API of the most recent stable compiler but employs a
+//! polyfill to provide that API consistently across any compiler since
+//! 1.15.0.
+//!
+//! [syn]: https://github.com/dtolnay/syn
+//! [quote]: https://github.com/dtolnay/quote
+//!
+//! # Usage
+//!
+//! The skeleton of a typical procedural macro typically looks like this:
+//!
+//! ```edition2018
+//! extern crate proc_macro;
+//!
+//! # const IGNORE: &str = stringify! {
+//! #[proc_macro_derive(MyDerive)]
+//! # };
+//! pub fn my_derive(input: proc_macro::TokenStream) -> proc_macro::TokenStream {
+//! let input = proc_macro2::TokenStream::from(input);
+//!
+//! let output: proc_macro2::TokenStream = {
+//! /* transform input */
+//! # input
+//! };
+//!
+//! proc_macro::TokenStream::from(output)
+//! }
+//! ```
+//!
+//! If parsing with [Syn], you'll use [`parse_macro_input!`] instead to
+//! propagate parse errors correctly back to the compiler when parsing fails.
+//!
+//! [`parse_macro_input!`]: https://docs.rs/syn/0.15/syn/macro.parse_macro_input.html
+//!
+//! # Unstable features
+//!
+//! The default feature set of proc-macro2 tracks the most recent stable
+//! compiler API. Functionality in `proc_macro` that is not yet stable is not
+//! exposed by proc-macro2 by default.
+//!
+//! To opt into the additional APIs available in the most recent nightly
+//! compiler, the `procmacro2_semver_exempt` config flag must be passed to
+//! rustc. As usual, we will polyfill those nightly-only APIs all the way back
+//! to Rust 1.15.0. As these are unstable APIs that track the nightly compiler,
+//! minor versions of proc-macro2 may make breaking changes to them at any time.
+//!

unit test. In order for helper libraries or components of a macro to be
testable in isolation, they must be implemented using `proc_macro2`.
-- **Provide the latest and greatest APIs across all compiler versions.**
- Procedural macros were first introduced to Rust in 1.15.0 with an extremely
- minimal interface. Since then, many improvements have landed to make macros
- more flexible and easier to write. This library tracks the procedural macro
- API of the most recent stable compiler but employs a polyfill to provide that

+Rust Quasi-Quoting
+==================
+
+[![Build Status](https://api.travis-ci.org/dtolnay/quote.svg?branch=master)](https://travis-ci.org/dtolnay/quote)
+[![Latest Version](https://img.shields.io/crates/v/quote.svg)](https://crates.io/crates/quote)
+[![Rust Documentation](https://img.shields.io/badge/api-rustdoc-blue.svg)](https://docs.rs/quote/)
+
+This crate provides the [`quote!`] macro for turning Rust syntax tree data
+structures into tokens of source code.
+
+[`quote!`]: https://docs.rs/quote/0.6/quote/macro.quote.html
+
+Procedural macros in Rust receive a stream of tokens as input, execute arbitrary
+Rust code to determine how to manipulate those tokens, and produce a stream of
+tokens to hand back to the compiler to compile into the caller's crate.
+Quasi-quoting is a solution to one piece of that -- producing tokens to return
+to the compiler.
+
+The idea of quasi-quoting is that we write *code* that we treat as *data*.
+Within the `quote!` macro, we can write what looks like code to our text editor
+or IDE. We get all the benefits of the editor's brace matching, syntax
+highlighting, indentation, and maybe autocompletion. But rather than compiling
+that as code into the current crate, we can treat it as data, pass it around,
+mutate it, and eventually hand it back to the compiler as tokens to compile into
+the macro caller's crate.
+
+This crate is motivated by the procedural macro use case, but is a
+general-purpose Rust quasi-quoting library and is not specific to procedural
+macros.
+
+*Version requirement: Quote supports any compiler version back to Rust's very
+first support for procedural macros in Rust 1.15.0.*
+
+[*Release notes*](https://github.com/dtolnay/quote/releases)
+
+```toml
+[dependencies]
+quote = "0.6"
+```
+
+## Syntax
+
+The quote crate provides a [`quote!`] macro within which you can write Rust code
+that gets packaged into a [`TokenStream`] and can be treated as data. You should
+think of `TokenStream` as representing a fragment of Rust source code.
+
+[`TokenStream`]: https://docs.rs/proc-macro2/0.4/proc_macro2/struct.TokenStream.html
+
+Within the `quote!` macro, interpolation is done with `#var`. Any type
+implementing the [`quote::ToTokens`] trait can be interpolated. This includes
+most Rust primitive types as well as most of the syntax tree types from [`syn`].
+
+[`quote::ToTokens`]: https://docs.rs/quote/0.6/quote/trait.ToTokens.html
+[`syn`]: https://github.com/dtolnay/syn
+
+```rust
+let tokens = quote! {
+ struct SerializeWith #generics #where_clause {
+ value: &'a #field_ty,
+ phantom: core::marker::PhantomData<#item_ty>,
+ }
+
+ impl #generics serde::Serialize for SerializeWith #generics #where_clause {
+ fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
+ where
+ S: serde::Serializer,
+ {
+ #path(self.value, serializer)
+ }
+ }
+
+ SerializeWith {
+ value: #value,
+ phantom: core::marker::PhantomData::<#item_ty>,
+ }
+};
+```
+
+## Repetition
+
+Repetition is done using `#(...)*` or `#(...),*` similar to `macro_rules!`. This
+iterates through the elements of any variable interpolated within the repetition
+and inserts a copy of the repetition body for each one. The variables in an
+interpolation may be anything that implements `IntoIterator`, including `Vec` or
+a pre-existing iterator.
+
+- `#(#var)*` — no separators
+- `#(#var),*` — the character before the asterisk is used as a separator
+- `#( struct #var; )*` — the repetition can contain other things
+- `#( #k => println!("{}", #v), )*` — even multiple interpolations
+
+Note that there is a difference between `#(#var ,)*` and `#(#var),*`—the latter
+does not produce a trailing comma. This matches the behavior of delimiters in
+`macro_rules!`.
+
+## Returning tokens to the compiler
+
+The `quote!` macro evaluates to an expression of type
+`proc_macro2::TokenStream`. Meanwhile Rust procedural macros are expected to
+return the type `proc_macro::TokenStream`.
+
+The difference between the two types is that `proc_macro` types are entirely
+specific to procedural macros and cannot ever exist in code outside of a
+procedural macro, while `proc_macro2` types may exist anywhere including tests
+and non-macro code like main.rs and build.rs. This is why even the procedural
+macro ecosystem is largely built around `proc_macro2`, because that ensures the
+libraries are unit testable and accessible in non-macro contexts.
+
+There is a [`From`]-conversion in both directions so returning the output of
+`quote!` from a procedural macro usually looks like `tokens.into()` or
+`proc_macro::TokenStream::from(tokens)`.
+
+[`From`]: https://doc.rust-lang.org/std/convert/trait.From.html
+
+## Examples
+
+### Combining quoted fragments
+
+Usually you don't end up constructing an entire final `TokenStream` in one
+piece. Different parts may come from different helper functions. The tokens
+produced by `quote!` themselves implement `ToTokens` and so can be interpolated
+into later `quote!` invocations to build up a final result.
+
+```rust
+let type_definition = quote! {...};
+let methods = quote! {...};
+
+let tokens = quote! {
+ #type_definition
+ #methods
+};
+```
+
+### Constructing identifiers
+
+Suppose we have an identifier `ident` which came from somewhere in a macro
+input and we need to modify it in some way for the macro output. Let's consider
+prepending the identifier with an underscore.
+
+Simply interpolating the identifier next to an underscore will not have the
+behavior of concatenating them. The underscore and the identifier will continue
+to be two separate tokens as if you had written `_ x`.
+
+```rust
+// incorrect
+quote! {
+ let mut _#ident = 0;
+}
+```
+
+The solution is to perform token-level manipulations using the APIs provided by
+Syn and proc-macro2.
+
+```rust
+let concatenated = format!("_{}", ident);
+let varname = syn::Ident::new(&concatenated, ident.span());
+quote! {
+ let mut #varname = 0;
+}
+```
+
+### Making method calls
+
+Let's say our macro requires some type specified in the macro input to have a
+constructor called `new`. We have the type in a variable called `field_type` of
+type `syn::Type` and want to invoke the constructor.
+
+```rust
+// incorrect
+quote! {
+ let value = #field_type::new();
+}
+```
+
+This works only sometimes. If `field_type` is `String`, the expanded code
+contains `String::new()` which is fine. But if `field_type` is something like
+`Vec<i32>` then the expanded code is `Vec<i32>::new()` which is invalid syntax.
+Ordinarily in handwritten Rust we would write `Vec::<i32>::new()` but for macros
+often the following is more convenient.
+
+```rust
+quote! {
+ let value = <#field_type>::new();
+}
+```
+
+This expands to `<Vec<i32>>::new()` which behaves correctly.
+
+A similar pattern is appropriate for trait methods.
+
+```rust
+quote! {
+ let value = <#field_type as core::default::Default>::default();
+}
+```
+
+## Hygiene
+
+Any interpolated tokens preserve the `Span` information provided by their
+`ToTokens` implementation. Tokens that originate within a `quote!` invocation
+are spanned with [`Span::call_site()`].
+
+[`Span::call_site()`]: https://docs.rs/proc-macro2/0.4/proc_macro2/struct.Span.html#method.call_site
+
+A different span can be provided explicitly through the [`quote_spanned!`]
+macro.
+
+[`quote_spanned!`]: https://docs.rs/quote/0.6/quote/macro.quote_spanned.html
+
+### Limitations
+
+- A non-repeating variable may not be interpolated inside of a repeating block
+ ([#7]).
+- The same variable may not be interpolated more than once inside of a repeating
+ block ([#8]).
+
+[#7]: https://github.com/dtolnay/quote/issues/7
+[#8]: https://github.com/dtolnay/quote/issues/8
+
+### Recursion limit
+
+The `quote!` macro relies on deep recursion so some large invocations may fail
+with "recursion limit reached" when you compile. If it fails, bump up the
+recursion limit by adding `#![recursion_limit = "128"]` to your crate. An even
+higher limit may be necessary for especially large invocations. You don't need
+this unless the compiler tells you that you need it.

+///
+/// Performs variable interpolation against the input and produces it as
+/// [`TokenStream`]. For returning tokens to the compiler in a procedural macro, use
+/// `into()` to build a `TokenStream`.
+///
+/// [`TokenStream`]: https://docs.rs/proc-macro2/0.4/proc_macro2/struct.TokenStream.html
+///
+/// # Interpolation
+///
+/// Variable interpolation is done with `#var` (similar to `$var` in
+/// `macro_rules!` macros). This grabs the `var` variable that is currently in
+/// scope and inserts it in that location in the output tokens. Any type
+/// implementing the [`ToTokens`] trait can be interpolated. This includes most
+/// Rust primitive types as well as most of the syntax tree types from the [Syn]
+/// crate.
+///
+/// [`ToTokens`]: trait.ToTokens.html
+/// [Syn]: https://github.com/dtolnay/syn
+///
+/// Repetition is done using `#(...)*` or `#(...),*` again similar to
+/// `macro_rules!`. This iterates through the elements of any variable
+/// interpolated within the repetition and inserts a copy of the repetition body
+/// for each one. The variables in an interpolation may be anything that
+/// implements `IntoIterator`, including `Vec` or a pre-existing iterator.
+///
+/// - `#(#var)*` — no separators
+/// - `#(#var),*` — the character before the asterisk is used as a separator
+/// - `#( struct #var; )*` — the repetition can contain other tokens
+/// - `#( #k => println!("{}", #v), )*` — even multiple interpolations
+///
+/// # Hygiene
+///
+/// Any interpolated tokens preserve the `Span` information provided by their
+/// `ToTokens` implementation. Tokens that originate within the `quote!`
+/// invocation are spanned with [`Span::call_site()`].
+///
+/// [`Span::call_site()`]: https://docs.rs/proc-macro2/0.4/proc_macro2/struct.Span.html#method.call_site
+///
+/// A different span can be provided through the [`quote_spanned!`] macro.
+///
+/// [`quote_spanned!`]: macro.quote_spanned.html
+///
+/// # Return type
+///
+/// The macro evaluates to an expression of type `proc_macro2::TokenStream`.
+/// Meanwhile Rust procedural macros are expected to return the type
+/// `proc_macro::TokenStream`.
+///
+/// The difference between the two types is that `proc_macro` types are entirely
+/// specific to procedural macros and cannot ever exist in code outside of a
+/// procedural macro, while `proc_macro2` types may exist anywhere including
+/// tests and non-macro code like main.rs and build.rs. This is why even the
+/// procedural macro ecosystem is largely built around `proc_macro2`, because
+/// that ensures the libraries are unit testable and accessible in non-macro
+/// contexts.
+///
+/// There is a [`From`]-conversion in both directions so returning the output of
+/// `quote!` from a procedural macro usually looks like `tokens.into()` or
+/// `proc_macro::TokenStream::from(tokens)`.
+///
+/// [`From`]: https://doc.rust-lang.org/std/convert/trait.From.html
+///
+/// # Examples
+///
+/// ## Procedural macro
+///
+/// The structure of a basic procedural macro is as follows. Refer to the [Syn]
+/// crate for further useful guidance on using `quote!` as part of a procedural
+/// macro.
+///
+/// [Syn]: https://github.com/dtolnay/syn
+///
+/// ```edition2018
+/// # #[cfg(any())]
+/// extern crate proc_macro;
+/// # use proc_macro2 as proc_macro;
+///
+/// use proc_macro::TokenStream;
+/// use quote::quote;
+///
+/// # const IGNORE_TOKENS: &'static str = stringify! {
+/// #[proc_macro_derive(HeapSize)]
+/// # };
+/// pub fn derive_heap_size(input: TokenStream) -> TokenStream {
+/// // Parse the input and figure out what implementation to generate...
+/// # const IGNORE_TOKENS: &'static str = stringify! {
+/// let name = /* ... */;
+/// let expr = /* ... */;
+/// # };
+/// #
+/// # let name = 0;
+/// # let expr = 0;
+///
+/// let expanded = quote! {
+/// // The generated impl.
+/// impl heapsize::HeapSize for #name {
+/// fn heap_size_of_children(&self) -> usize {
+/// #expr
+/// }
+/// }
+/// };
+///
+/// // Hand the output tokens back to the compiler.
+/// TokenStream::from(expanded)
+/// }
+/// ```
+///
+/// ## Combining quoted fragments
+///
+/// Usually you don't end up constructing an entire final `TokenStream` in one
+/// piece. Different parts may come from different helper functions. The tokens
+/// produced by `quote!` themselves implement `ToTokens` and so can be
+/// interpolated into later `quote!` invocations to build up a final result.
+///
+/// ```edition2018
+/// # use quote::quote;
+/// #
+/// let type_definition = quote! {...};
+/// let methods = quote! {...};
+///
+/// let tokens = quote! {
+/// #type_definition
+/// #methods
+/// };
+/// ```
+///
+/// ## Constructing identifiers
+///
+/// Suppose we have an identifier `ident` which came from somewhere in a macro
+/// input and we need to modify it in some way for the macro output. Let's
+/// consider prepending the identifier with an underscore.
+///
+/// Simply interpolating the identifier next to an underscore will not have the
+/// behavior of concatenating them. The underscore and the identifier will
+/// continue to be two separate tokens as if you had written `_ x`.
+///
+/// ```edition2018
+/// # use proc_macro2::{self as syn, Span};
+/// # use quote::quote;
+/// #
+/// # let ident = syn::Ident::new("i", Span::call_site());
+/// #
+/// // incorrect
+/// quote! {
+/// let mut _#ident = 0;
+/// }
+/// # ;
+/// ```
+///
+/// The solution is to perform token-level manipulations using the APIs provided
+/// by Syn and proc-macro2.
+///
+/// ```edition2018
+/// # use proc_macro2::{self as syn, Span};
+/// # use quote::quote;
+/// #
+/// # let ident = syn::Ident::new("i", Span::call_site());
+/// #
+/// let concatenated = format!("_{}", ident);
+/// let varname = syn::Ident::new(&concatenated, ident.span());
+/// quote! {
+/// let mut #varname = 0;
+/// }
+/// # ;
+/// ```
+///
+/// ## Making method calls
+///
+/// Let's say our macro requires some type specified in the macro input to have
+/// a constructor called `new`. We have the type in a variable called
+/// `field_type` of type `syn::Type` and want to invoke the constructor.
+///
+/// ```edition2018
+/// # use quote::quote;
+/// #
+/// # let field_type = quote!(...);
+/// #
+/// // incorrect
+/// quote! {
+/// let value = #field_type::new();
+/// }
+/// # ;
+/// ```
+///
+/// This works only sometimes. If `field_type` is `String`, the expanded code
+/// contains `String::new()` which is fine. But if `field_type` is something
+/// like `Vec<i32>` then the expanded code is `Vec<i32>::new()` which is invalid
+/// syntax. Ordinarily in handwritten Rust we would write `Vec::<i32>::new()`
+/// but for macros often the following is more convenient.
+///
+/// ```edition2018
+/// # use quote::quote;
+/// #
+/// # let field_type = quote!(...);
+/// #
+/// quote! {
+/// let value = <#field_type>::new();
+/// }
+/// # ;
+/// ```
+///
+/// This expands to `<Vec<i32>>::new()` which behaves correctly.
+///
+/// A similar pattern is appropriate for trait methods.
+///
+/// ```edition2018
+/// # use quote::quote;
+/// #
+/// # let field_type = quote!(...);
+/// #
+/// quote! {
+/// let value = <#field_type as core::default::Default>::default();
+/// }
+/// # ;
+/// ```
+#[macro_export(local_inner_macros)]
+macro_rules! quote {
+ ($($tt:tt)*) => (quote_spanned!($crate::__rt::Span::call_site()=> $($tt)*));
+}
+
+/// Same as `quote!`, but applies a given span to all tokens originating within
+/// the macro invocation.
+///
+/// # Syntax
+///
+/// A span expression of type [`Span`], followed by `=>`, followed by the tokens
+/// to quote. The span expression should be brief -- use a variable for anything
+/// more than a few characters. There should be no space before the `=>` token.
+///
+/// [`Span`]: https://docs.rs/proc-macro2/0.4/proc_macro2/struct.Span.html
+///
+/// ```edition2018
+/// # use proc_macro2::Span;
+/// # use quote::quote_spanned;
+/// #
+/// # const IGNORE_TOKENS: &'static str = stringify! {
+/// let span = /* ... */;
+/// # };
+/// # let span = Span::call_site();
+/// # let init = 0;
+///
+/// // On one line, use parentheses.
+/// let tokens = quote_spanned!(span=> Box::into_raw(Box::new(#init)));
+///
+/// // On multiple lines, place the span at the top and use braces.
+/// let tokens = quote_spanned! {span=>
+/// Box::into_raw(Box::new(#init))
+/// };
+/// ```
+///
+/// The lack of space before the `=>` should look jarring to Rust programmers
+/// and this is intentional. The formatting is designed to be visibly
+/// off-balance and draw the eye a particular way, due to the span expression
+/// being evaluated in the context of the procedural macro and the remaining
+/// tokens being evaluated in the generated code.
+///
+/// # Hygiene
+///
+/// Any interpolated tokens preserve the `Span` information provided by their
+/// `ToTokens` implementation. Tokens that originate within the `quote_spanned!`
+/// invocation are spanned with the given span argument.
+///
+/// # Example
+///
+/// The following procedural macro code uses `quote_spanned!` to assert that a
+/// particular Rust type implements the [`Sync`] trait so that references can be
+/// safely shared between threads.
+///
+/// [`Sync`]: https://doc.rust-lang.org/std/marker/trait.Sync.html
+///
+/// ```edition2018
+/// # use quote::{quote_spanned, TokenStreamExt, ToTokens};
+/// # use proc_macro2::{Span, TokenStream};
+/// #
+/// # struct Type;
+/// #
+/// # impl Type {
+/// # fn span(&self) -> Span {
+/// # Span::call_site()
+/// # }
+/// # }
+/// #
+/// # impl ToTokens for Type {
+/// # fn to_tokens(&self, _tokens: &mut TokenStream) {}
+/// # }
+/// #
+/// # let ty = Type;
+/// # let call_site = Span::call_site();
+/// #
+/// let ty_span = ty.span();
+/// let assert_sync = quote_spanned! {ty_span=>
+/// struct _AssertSync where #ty: Sync;
+/// };
+/// ```
+///
+/// If the assertion fails, the user will see an error like the following. The
+/// input span of their type is hightlighted in the error.
+///
+/// ```text
+/// error[E0277]: the trait bound `*const (): std::marker::Sync` is not satisfied
+/// --> src/main.rs:10:21
+/// |
+/// 10 | static ref PTR: *const () = &();
+/// | ^^^^^^^^^ `*const ()` cannot be shared between threads safely
+/// ```
+///
+/// In this example it is important for the where-clause to be spanned with the
+/// line/column information of the user's input type so that error messages are
+/// placed appropriately by the compiler. But it is also incredibly important
+/// that `Sync` resolves at the macro definition site and not the macro call
+/// site. If we resolve `Sync` at the same span that the user's type is going to
+/// be resolved, then they could bypass our check by defining their own trait
+/// named `Sync` that is implemented for their type.

+/// Formatting macro for constructing `Ident`s.
+///
+/// <br>
+///
+/// # Syntax
+///
+/// Syntax is copied from the [`format!`] macro, supporting both positional and
+/// named arguments.
+///
+/// Only a limited set of formatting traits are supported. The current mapping
+/// of format types to traits is:
+///
+/// * `{}` ⇒ [`IdentFragment`]
+/// * `{:o}` ⇒ [`Octal`](`std::fmt::Octal`)
+/// * `{:x}` ⇒ [`LowerHex`](`std::fmt::LowerHex`)
+/// * `{:X}` ⇒ [`UpperHex`](`std::fmt::UpperHex`)
+/// * `{:b}` ⇒ [`Binary`](`std::fmt::Binary`)
+///
+/// See [`std::fmt`] for more information.
+///
+/// <br>
+///
+/// # IdentFragment
+///
+/// Unlike `format!`, this macro uses the [`IdentFragment`] formatting trait by
+/// default. This trait is like `Display`, with a few differences:
+///
+/// * `IdentFragment` is only implemented for a limited set of types, such as
+/// unsigned integers and strings.
+/// * [`Ident`] arguments will have their `r#` prefixes stripped, if present.
+///
+/// [`Ident`]: `proc_macro2::Ident`
+///
+/// <br>
+///
+/// # Hygiene
+///
+/// The [`Span`] of the first `Ident` argument is used as the span of the final
+/// identifier, falling back to [`Span::call_site`] when no identifiers are
+/// provided.
+///
+/// ```
+/// # use quote::format_ident;
+/// # let ident = format_ident!("Ident");
+/// // If `ident` is an Ident, the span of `my_ident` will be inherited from it.
+/// let my_ident = format_ident!("My{}{}", ident, "IsCool");
+/// assert_eq!(my_ident, "MyIdentIsCool");
+/// ```
+///
+/// Alternatively, the span can be overridden by passing the `span` named
+/// argument.
+///
+/// ```
+/// # use quote::format_ident;
+/// # const IGNORE_TOKENS: &'static str = stringify! {
+/// let my_span = /* ... */;
+/// # };
+/// # let my_span = proc_macro2::Span::call_site();
+/// format_ident!("MyIdent", span = my_span);
+/// ```
+///
+/// [`Span`]: `proc_macro2::Span`
+/// [`Span::call_site`]: `proc_macro2::Span::call_site`
+///
+/// <p><br></p>
+///
+/// # Panics
+///
+/// This method will panic if the resulting formatted string is not a valid
+/// identifier.
+///
+/// <br>
+///
+/// # Examples
+///
+/// Composing raw and non-raw identifiers:
+/// ```
+/// # use quote::format_ident;
+/// let my_ident = format_ident!("My{}", "Ident");
+/// assert_eq!(my_ident, "MyIdent");
+///
+/// let raw = format_ident!("r#Raw");
+/// assert_eq!(raw, "r#Raw");
+///
+/// let my_ident_raw = format_ident!("{}Is{}", my_ident, raw);
+/// assert_eq!(my_ident_raw, "MyIdentIsRaw");
+/// ```
+///
+/// Integer formatting options:
+/// ```
+/// # use quote::format_ident;
+/// let num: u32 = 10;
+///
+/// let decimal = format_ident!("Id_{}", num);
+/// assert_eq!(decimal, "Id_10");

+# The Rust Code of Conduct
+
+A version of this document [can be found online](https://www.rust-lang.org/conduct.html).
+
+## Conduct
+
+**Contact**: [rust-mods@rust-lang.org](mailto:rust-mods@rust-lang.org)
+
+* We are committed to providing a friendly, safe and welcoming environment for all, regardless of level of experience, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, nationality, or other similar characteristic.
+* On IRC, please avoid using overtly sexual nicknames or other nicknames that might detract from a friendly, safe and welcoming environment for all.
+* Please be kind and courteous. There's no need to be mean or rude.
+* Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
+* Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
+* We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior. We interpret the term "harassment" as including the definition in the <a href="http://citizencodeofconduct.org/">Citizen Code of Conduct</a>; if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don't tolerate behavior that excludes people in socially marginalized groups.
+* Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact one of the channel ops or any of the [Rust moderation team][mod_team] immediately. Whether you're a regular contributor or a newcomer, we care about making this community a safe place for you and we've got your back.
+* Likewise any spamming, trolling, flaming, baiting or other attention-stealing behavior is not welcome.
+
+## Moderation
+
+
+These are the policies for upholding our community's standards of conduct. If you feel that a thread needs moderation, please contact the [Rust moderation team][mod_team].
+
+1. Remarks that violate the Rust standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner.)
+2. Remarks that moderators find inappropriate, whether listed in the code of conduct or not, are also not allowed.
+3. Moderators will first respond to such remarks with a warning.
+4. If the warning is unheeded, the user will be "kicked," i.e., kicked out of the communication channel to cool off.
+5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded.
+6. Moderators may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology.
+7. If a moderator bans someone and you think it was unjustified, please take it up with that moderator, or with a different moderator, **in private**. Complaints about bans in-channel are not allowed.
+8. Moderators are held to a higher standard than other community members. If a moderator creates an inappropriate situation, they should expect less leeway than others.
+
+In the Rust community we strive to go the extra step to look out for each other. Don't just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they're off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely.
+
+And if someone takes issue with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could've communicated better — remember that it's your responsibility to make your fellow Rustaceans comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust.
+
+The enforcement policies listed above apply to all official Rust venues; including official IRC channels (#rust, #rust-internals, #rust-tools, #rust-libs, #rustc, #rust-beginners, #rust-docs, #rust-community, #rust-lang, and #cargo); GitHub repositories under rust-lang, rust-lang-nursery, and rust-lang-deprecated; and all forums under rust-lang.org (users.rust-lang.org, internals.rust-lang.org). For other projects adopting the Rust Code of Conduct, please contact the maintainers of those projects for enforcement. If you wish to use this code of conduct for your own project, consider explicitly mentioning your moderation policy or making a copy with your own moderation policy so as to avoid confusion.
+
+*Adapted from the [Node.js Policy on Trolling](http://blog.izs.me/post/30036893703/policy-on-trolling) as well as the [Contributor Covenant v1.3.0](https://www.contributor-covenant.org/version/1/3/0/).*

+# rustc-hash
+
+A speedy hash algorithm used within rustc. The hashmap in liballoc by
+default uses SipHash which isn't quite as speedy as we want. In the
+compiler we're not really worried about DOS attempts, so we use a fast
+non-cryptographic hash.
+
+This is the same as the algorithm used by Firefox -- which is a
+homespun one not based on any widely-known algorithm -- though
+modified to produce 64-bit hash values instead of 32-bit hash
+values. It consistently out-performs an FNV-based hash within rustc
+itself -- the collision rate is similar or slightly worse than FNV,
+but the speed of the hash function itself is much higher because it
+works on up to 8 bytes at a time.
+
+## Usage
+
+```
+use rustc_hash::FxHashMap;
+let map: FxHashMap<u32, u32> = FxHashMap::default();
+```
