Ticker utilities for Golang - extensions of the standard library's time.Ticker.
Create constant, linear, or exponential tickers. Optionally configure random
jitter, minimum or maximum intervals, and maximum cumulative duration. See the
examples_test.go for comprehensive usage.
go get github.com/tkennon/ticker
Create tickers that fire at linearly or exponentially increasing intervals. A
constant ticker is also included that is functionally equivalent to a
time.Ticker. Once started, tickers must be stopped in order to clean up
resources.
t := ticker.NewExponential(time.Second, 2.0). // Create a ticker starting at one second whose intervals double each time it fires.
WithMaxInterval(time.Hour) // Optionally cap the maximum interval to an hour.
WithJitter(0.1) // Optionally add a +/-10% jitter to each interval.
if err := t.Start(); err != nil {
return err
}
defer t.Stop()
for range t.C {
// Do something each time the ticker fires. Note that because we have not
// added a context to the ticker, and we have not specified a maximum total
// duration through WithMaxDuration(), the ticker will tick forever.
}v1.0.0 is tagged and considered stable.
