go多路复用功能

大家在工作中使用go语言都是因为go语言中提供方便又简介的协成吧，只需一个go关键字就可以开启一个协成，今天为大家推荐一种go实现的多路复用代码，大家可以参考一下呀可以下方评论留言呦

package test_7

import (
	"fmt"
	"testing"
)

type binOp func(a, b int) int

func TestGoAll(t *testing.T) {
	adder := startServer(func(a, b int) int { return a + b })
	const N = 100
	var reqs [N]Request
	for i := 0; i < N; i++ {
		req := &reqs[i]
		req.a = i
		req.b = i + N
		req.replay = make(chan int)
		adder <- req
	}
	for i := N - 1; i >= 0; i-- {
		if <-reqs[i].replay != N+2*i {
			fmt.Println("failed at", i)
		} else {
			fmt.Println("Request", i, "is ok!")

		}
	}
	fmt.Println("done")
}

type Request struct {
	a, b   int
	replay chan int
}

func run(op binOp, req *Request) {
	req.replay <- op(req.a, req.b)
}

func server(op binOp, service chan *Request) {
	for {
		rep := <-service
		go run(op, rep)
	}
}
func startServer(op binOp) chan *Request {
	reqChan := make(chan *Request)
	go server(op, reqChan)
	return reqChan
}
