concurrent
- 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
m := concurrent.NewMap()
m.Store("hello", "world")
elem, found := m.Load("hello")
// elem will be "world"
// found will be true
concurrent.Executor
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
