Go 问题请教

有大佬可以帮忙看看 SendToProc 这个函数里 select+slice 会 panic 吗？感谢感谢🙏

func init() {
	Chan = make(chan *GenData, 500000)
}

var Chan chan *GenData

type SendQueue struct {
	queue []*GenData
	size  int
}

type GenData struct {
	s string
}

func SendToProc() error {
	go func() {
		batchSize := 100
		tc := time.NewTicker(time.Millisecond * 100)
		sq := &SendQueue{
			queue: make([]*GenData, 0),
			size:  0,
		}
		for {
			select {
			case g := <-Chan:
				sq.queue = append(sq.queue, g)
				sq.size++
				if sq.size == batchSize {
					send(sq.queue)
					sq.queue = sq.queue[:0]
					sq.size = 0
				}
			case <-tc.C:
				if sq.size > 0 {
					send(sq.queue)
					sq.queue = sq.queue[:0]
					sq.size = 0
				}
			}
		}
	}()
	return nil
}

func send(sendList []*GenData) {
	for i, v := range sendList {
		fmt.Println(i, v)
	}
}
