Hands-On System Programming with Go

Sending, receiving, and closing

The reflect.Value type offers a few methods that have to be used exclusively with channels, Send and Recv for sending and receiving, and Close for closing channels. Let's take a look at a sample use case of these functions and methods:

func main() {    t := reflect.ChanOf(reflect.BothDir, reflect.TypeOf(""))    v := reflect.MakeChan(t, 0)    go func() {        for i := 0; i < 10; i++ {            v.Send(reflect.ValueOf(fmt.Sprintf("msg-%d", i)))        }        v.Close()    }()    for msg, ok := v.Recv(); ok; msg, ok = v.Recv() {        fmt.Println(msg)    }}
