模式1 Generator:返回channel的函数 package main import ( "fmt" "math/rand" "time" ) func main() { c := boring("boring!") // Function returning a channel. for i := 0; i < 5; i++ { fmt.Printf("You say: %q\n", <-c) } fmt.Println("You're boring; I'm leaving.") }...
} Once the caller is done with the generator (when it breaks the loop), the goroutine will run forever executing the infinite loop. Our code will leak a goroutine. We can avoid the problem by signaling the internal goroutine with a stop channel but there is a better solution: cancellable...
原文地址:https://blog.golang.org/go-co... 并发编程有自己的一些习惯用语,超时就是其中之一。虽然 Golang 的管道并没有直接支持超时,但是实现起来并不难。假设遇到了这样一种场景:在从 管道 ch 中取值之前至少等待 1 秒钟。我们可以创建一个管道用来传递信号,开启一个协程休眠一秒钟,然后给管道传递一个值。
Go Concurrency Patterns: Timing out, moving on Andrew Gerrand 23 September 2010 内容 Concurrent programming has its own idioms. A good example is timeouts. Although Go’s channels do not support them directly, they are easy to implement. Say we want to receive from the channel ch, but want...
Andrew Gerrand 23 September 2010 Concurrent programming has its own idioms. A good example is timeouts. Although Go’s channels do not support them directly, they are easy to implement. Say we want to receive from the channelch, but want to wait at most one second for the value to arrive...
