示例

	waitCallback := NewCallback()
	wg := sync.WaitGroup{}
	wg.Add(2)
	key := "ding"
	value := "dong"
	go func() {
		defer wg.Done()
		got := waitCallback.PushWait(context.Background(), key)
		fmt.Println(got)
	}()

	// 真实场景应该在其他地方异步调 waitCallback.Resolve(key, value)
	{
		time.Sleep(time.Millisecond)
		go func() {
			defer wg.Done()
			waitCallback.Resolve(key, value)
		}()
	}

	wg.Wait()
