* 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 |
