- Keep using the same hyper client instead of building a new one for
each request
- This allows the client to reuse connections and improves the
performance of multiple requests by almost 2x.
- The playlist_tracks example takes 38 secs before and 20 secs after the
change to enumerate a 180 track playlist
- To avoid carrying the hyper Client generics through the whole project,
`ProxyConnector` is always used as the Connector, but disabled when
not using a proxy.
- The client creation is done lazily to keep the `HttpClient::new`
without a `Result` return type
- Fixed resolve function panicking when resolving endpoint type with no
AP in the list
- Fixed fallback APs not being applied when only some of the AP types
were missing
- Switch container type from `Vec` to `VecDeque` for the `AccessPoints`
- Remove the note about fallback AP being used even if the port is not
matching the configured `ap_port`
- Change the return type of metadata convenience iter functions to
actual iterators instead of allocated collections
- The iterator item type is set to be a reference
- Also fix an overflow panic when a token cannot be parsed.
- Getting tokens always requires the keymaster client ID;
passing the actual client ID yields a HashCash challenge.
- `from_repeated_message` -> `impl_from_repeated`
- `from_repeated_enum` -> `impl_from_repeated_copy` since the enum
references were just simply deref copied
- `try_from_repeated_message` -> `impl_try_from_repeated`
- Simplified the implementation of `from_repeated_enum`
- Added `*-current()` functions to `Artist` to get the list of current
versions / releases of each album
- This is useful since the `AlbumGroups` can contain multiple versions
/ releases of the same album
- Derive `Default` trait for the vec / hashmap wrapper types in
`librespot-metadata`
- The wrapped types (`Vec` / `Hashmap`) implement Default, so the
wrapper types should as well
