我是否需要明确停止报价已重新分配的股票行情？

Question

I'm using time.Ticker to do some stuff at a regular interval. I want to be able to change the frequency that stuff happens at:

for {
        select {
        case <-ticker.C:
            //do stuff
        case t := <-newTicker:
            oldTicker := ticker
            ticker = t
            oldTicker.Stop()
        }
    }

Do I need that ticker cleanup to avoid a memory leak, or will reassigning ticker like

case ticker := <-newTicker:

be enough?

Answer 1

As JimB mentioned as per time package GoDoc.

Under time.NewTicker, the following is mentioned.

Stop the ticker to release associated resources.

Provided you run oldTimer.Stop(), oldTicker will get garbage collected after exiting the case statement as it's out of scope.
