Description
Repeater calls a function until it returns no error, up to some number of iterations and delays defined by strategy. It terminates immediately on err from the provided (optional) list of critical errors.

Repeater

Repeater calls a function until it returns no error, up to some number of iterations and delays defined by strategy. It terminates immediately on err from the provided (optional) list of critical errors.
Install and update
go get -u github.com/go-pkgz/repeater
How to use
New Repeater created by New(strtg strategy.Interface)
or shortcut for default - NewDefault(repeats int, delay time.Duration) *Repeater
.
To activate invoke Do
method. Do
repeats func until no error returned. Predefined (optional) errors terminate the loop immediately.
func (r Repeater) Do(ctx context.Context, fun func() error, errors ...error) (err error)
Repeating strategy
User can provide his own strategy implementing the interface:
type Interface interface {
Start(ctx context.Context) chan struct{}
}
Returned channels used as "ticks," i.e., for each repeat or initial operation one read from this channel needed. Closing the channel indicates "done with retries." It is pretty much the same idea as time.Timer
or time.Tick
implements. Note - the first (technically not-repeated-yet) call won't happen until something sent to the channel. For this reason, the typical strategy sends the first "tick" before the first wait/sleep.
Three strategies provided byt the package:
- Fixed delay, up to max number of attempts. It is the default strategy used by
repeater.NewDefault
constructor. - BackOff with jitter provides an exponential backoff. It starts from
Duration
interval and goes in steps withlast * math.Pow(factor, attempt)
. Optional jitter randomizes intervals a little. Factor = 1 effectively makes this strategy fixed withDuration
delay. - Once strategy does not do any repeats and mainly used for tests/mocks`.
