+A high-performance 100% compatible drop-in replacement of "encoding/json"
+
+# Benchmark
+
+
+
+Source code: https://github.com/json-iterator/go-benchmark/blob/master/src/github.com/json-iterator/go-benchmark/benchmark_medium_payload_test.go
+
+Raw Result (easyjson requires static code generation)
+
+| | ns/op | allocation bytes | allocation times |
+| --------------- | ----------- | ---------------- | ---------------- |
+| std decode | 35510 ns/op | 1960 B/op | 99 allocs/op |
+| easyjson decode | 8499 ns/op | 160 B/op | 4 allocs/op |
+| jsoniter decode | 5623 ns/op | 160 B/op | 3 allocs/op |
+| std encode | 2213 ns/op | 712 B/op | 5 allocs/op |
+| easyjson encode | 883 ns/op | 576 B/op | 3 allocs/op |
+| jsoniter encode | 837 ns/op | 384 B/op | 4 allocs/op |
+
+Always benchmark with your own workload.
+The result depends heavily on the data input.

+* concurrent.Executor: goroutine with explicit ownership and cancellable
+
+# concurrent.Map
+
+because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable
+
+```go
+m := concurrent.NewMap()
+m.Store("hello", "world")
+elem, found := m.Load("hello")
+// elem will be "world"
+// found will be true
+```
+

+executor.Go(func(ctx context.Context) {
+ everyMillisecond := time.NewTicker(time.Millisecond)
+ for {
+ select {
+ case <-ctx.Done():

+ return
+ case <-everyMillisecond.C:
+ // do something
+ }
+ }
+})
+time.Sleep(time.Second)
+executor.StopAndWaitForever()
+fmt.Println("executor stopped")
+```
+
+attach goroutine to executor instance, so that we can
+
+* cancel it by stop the executor with Stop/StopAndWait/StopAndWaitForever
+* handle panic by callback: the default behavior will no longer crash your application

+
+reflect api that avoids runtime reflect.Value cost
+
+* reflect get/set interface{}, with type checking
+* reflect get/set unsafe.Pointer, without type checking
+* `reflect2.TypeByName` works like `Class.forName` found in java
+
+[json-iterator](https://github.com/json-iterator/go) use this package to save runtime dispatching cost.
+This package is designed for low level libraries to optimize reflection performance.
+General application should still use reflect standard library.
+
+# reflect2.TypeByName
+
+```go
+// given package is github.com/your/awesome-package
+type MyStruct struct {
+ // ...
+}
+
+// will return the type
+reflect2.TypeByName("awesome-package.MyStruct")
+// however, if the type has not been used
+// it will be eliminated by compiler, so we can not get it in runtime
+```
+
+# reflect2 get/set interface{}
+
+```go
+valType := reflect2.TypeOf(1)
+i := 1
+j := 10
+valType.Set(&i, &j)
+// i will be 10
+```
+
+to get set `type`, always use its pointer `*type`
+
+# reflect2 get/set unsafe.Pointer
+
+```go
+valType := reflect2.TypeOf(1)
+i := 1
+j := 10
+valType.UnsafeSet(unsafe.Pointer(&i), unsafe.Pointer(&j))
+// i will be 10
+```
+
+to get set `type`, always use its pointer `*type`
+
+# benchmark
+
+Benchmark is not necessary for this package. It does nothing actually.
+As it is just a thin wrapper to make go runtime public.
+Both `reflect2` and `reflect` call same function
+provided by `runtime` package exposed by go language.
+
+# unsafe safety
+
+Instead of casting `[]byte` to `sliceHeader` in your application using unsafe.
+We can use reflect2 instead. This way, if `sliceHeader` changes in the future,
+only reflect2 need to be upgraded.
+
+reflect2 tries its best to keep the implementation same as reflect (by testing).
