This implementation provides a fast pure-Go implementation and an even faster
assembly implementation for amd64.
The package is written with optimized pure Go and also contains even faster
assembly implementations for amd64 and arm64. If desired, the `purego` build tag
opts into using the Go code even on those architectures.

### Health middleware
Responds with the status 200 if all health checks passed, 503 if any failed. Both health path and check functions passed by consumer.
For production usage this middleware should be used with throttler/limiter and, optionally, with some auth middlewares
Example of usage:
```go
check1 := func(ctx context.Context) (name string, err error) {
// do some check, for example check DB connection
return "check1", nil // all good, passed
}
check2 := func(ctx context.Context) (name string, err error) {
// do some other check, for example ping an external service
return "check2", errors.New("some error") // check failed
}
router := chi.NewRouter()
router.Use(rest.Health("/health", check1, check2))
```
example of the actual call and response:
```
> http GET https://example.com/health

_this middleware is pretty basic, but can be used for simple health checks. For more complex cases, like async/cached health checks see [alexliesenfeld/health](https://github.com/alexliesenfeld/health)_
### Logger middleware
Logs request, request handling time and response. Log record fields in order of occurrence:
@ -119,6 +158,23 @@ Maybe middleware will allow you to change the flow of the middleware stack execu
value of maybeFn(request). This is useful for example if you'd like to skip a middleware handler if
a request does not satisfy the maybeFn logic.
### Reject middleware
Reject is a middleware that rejects requests with a given status code and message based on a user-defined function.
This is useful for example if you'd like to reject requests to a particular resource based on a request header, or want to implement a conditional request handler based on service parameters.
example with chi router:
```go
router := chi.NewRouter()
rejectFn := func(r *http.Request) (bool) {
return r.Header.Get("X-Request-Id") == "" // reject if no X-Request-Id header
}
router.Use(rest.Reject(http.StatusBadRequest, "X-Request-Id header is required", rejectFn))
```
### Benchmarks middleware
Benchmarks middleware allows to measure the time of request handling, number of request per second and report aggregated metrics. This middleware keeps track of the request in the memory and keep up to 900 points (15 minutes, data-point per second).

| std decode | 35510 ns/op | 1960 B/op | 99 allocs/op |

Always benchmark with your own workload.
The result depends heavily on the data input.
# Usage
100% compatibility with standard lib
Replace
```go
import "encoding/json"
json.Marshal(&data)
```
with
```go
import jsoniter "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(&data)
```
Replace
```go
import "encoding/json"
json.Unmarshal(input, &data)
```
with
```go
import jsoniter "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Unmarshal(input, &data)
```

// Package jsoniter implements encoding and decoding of JSON as defined in

// "JSON and Go"
// (https://golang.org/doc/articles/json_and_go.html)
// gives a description of how Marshal/Unmarshal operate
// between arbitrary or predefined json objects and bytes,

//
// Besides, jsoniter.Iterator provides a different set of interfaces
// iterating given bytes/string/reader

* concurrent.Map: backport sync.Map for go below 1.9
* 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
```
# concurrent.Executor
```go
executor := concurrent.NewUnboundedExecutor()
executor.Go(func(ctx context.Context) {
everyMillisecond := time.NewTicker(time.Millisecond)
for {
select {
case <-ctx.Done():
fmt.Println("goroutine exited")
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).
