go自编自导自写一片协成池

近段时间，在用go的时候找了许久没有发现go协成池之类的东西，然后自己脑子一热，手撸的一个协成池，希望这个东西可以帮助到，也在go语言中苦苦寻求go协成池的伙伴，有什么想法可以留言到下面

func TestGoPoll(t *testing.T) {
	task := NewTask(func() error {
		fmt.Println(time.Now())
		return nil
	})
	taskCount := 0
	ticker := time.NewTicker(2 * time.Second)
	p := NewWorkPool(3)
	go func(c *time.Ticker) {
		for {
			p.TaskQueue <- task
			<-c.C
			taskCount++
			if taskCount == 5 {
				p.close()
				break
			}
		}
		return
	}(ticker)
	p.run()
}

type Task struct {
	f func() error
}

func NewTask(f func() error) *Task {
	return &Task{f: f}
}

type WorkPool struct {
	TaskQueue chan *Task
	workNum   int
	shop      chan struct{}
}

func NewWorkPool(cap int) *WorkPool {
	if cap <= 0 {
		cap = 10
	}
	return &WorkPool{
		TaskQueue: make(chan *Task),
		workNum:   cap,
		shop:      make(chan struct{}),
	}
}

func (t *Task) Execute() error {
	return t.f()
}

func (p *WorkPool) worker(workerId int) {
	for task := range p.TaskQueue {
		err := task.Execute()
		if err != nil {
			fmt.Println(err)
			continue
		}
		fmt.Printf("worker %d finished\n", workerId)
	}
}

func (p *WorkPool) run() {
	for i := 0; i < p.workNum; i++ {
		go p.worker(i)
	}
	<-p.shop
}

func (p *WorkPool) close() {
	p.shop <- struct{}{}
}
