英文:
time.NewTimer vs time.Tick
问题
文档指出time.Tick会泄漏（“请注意，如果没有关闭的方法，底层的 Ticker 将无法被垃圾回收器回收，它会“泄漏”）。我猜这是指通道。然而，似乎没有办法清理Timer：你可以确保它不触发，但你无法关闭通道（只能接收）。
代码中没有close调用。runtime.deltimer（Stop的底层机制）也不会触及通道。
无论如何，Timer是否总是会泄漏？
英文:
The documentation indicates the time.Tick leaks ('be aware that without a way to shut it down the underlying Ticker cannot be recovered by the garbage collector; it "leaks"'). I'm assuming this refers to the channel. However, there appears to be no way to cleanup a Timer, either: You can make sure it doesn't fire but you can't close the channel (receive only).
The code for it doesn't contain a close call. runtime.deltimer (which is the underlying mechanism for Stop) doesn't touch the channel either.
No matter what, does Timer always leak?

唯一重要的清理是通过调用Stop方法来完成的（正如@JimB所提到的）。
英文:
The only cleanup that matters is performed by calling Stop (as mentioned by @JimB).
