broadcaster:使用 Go 的有效负载广播（一对多，扇出）消息

# broadcaster This package implements broadcast type messaging (or event) in a Go idiomatic way not based on a list of handlers. This is based on the design invented by [Roger Peppe](https://rogpeppe.wordpress.com/2009/12/01/concurrent-idioms-1-broadcasting-values-in-go-with-linked-channels/) and the actual implementation from the [gibb package](https://github.com/dagoof/gibb), modified to only expose channels, which are the prefered way of communicating in Go. Contrary to ordinary packages which use a list of channels and register/unregister methods, this package makes use of a linked list of channels to broadcast values in a fanout way. ## Install ``` $ go get github.com/steeve/broadcaster ``` ## How to use ```go package main import ( "fmt" "github.com/steeve/broadcaster" ) func main() { b := broadcaster.NewBroadcaster() defer b.Close() for i := 0; i < 10; i++ { go func() { read, done := b.Listen() defer close(done) fmt.Println(<-read) }() } b.Broadcast("sample payload") } ```
