    if b == 0 {
        return errors.New("div zero")
    }
    return nil
}

func main() {
    f1 := fetry.NewFetry(Div, 9, time.Second, 1, 0)
    f2 := fetry.NewFetry(Div, 3, 3*time.Second, 3, 0)
    q := fetry.NewQueue()
    q.Push(f1)
    time.Sleep(2 * time.Second)
    q.Push(f2)
    time.Sleep(time.Minute)
    q.Exit()
