Golang : Timeout example
It is important for programs to know when to abort when connecting to external resources. One such example is the net.DialTimeout()
function and if you looking to implement timeout feature in Golang, it is pretty easy with channels and select.
This code example below simulates a situation when a timeout occurred.
package main
import (
"fmt"
"time"
)
func main() {
c := make(chan bool, 1)
go func() {
select {
case m := <-c:
// do something
handle(m)
case <-time.After(3 * time.Second):
fmt.Println("timed out")
}
}()
time.Sleep(5 * time.Second)
}
func handle(m bool) {}
