Functions

func DefaultBackoff

func DefaultBackoff() backoff.Func

0ms, 100 ms, 200 ms, 400 ms, 800 ms, 1000 ms, 1000 ms, ...

func ErrorsToLogger

func ErrorsToLogger(logger *log.Logger) func(error)

creates `Retry()` compatible error handler function that just pushes errors to a logger

func IgnoreErrorsWithin

func IgnoreErrorsWithin(expectErrorsWithin time.Duration, handleError func(error)) func(error)

creates `Retry()` compatible error handler that only starts reacting to errors after a specific initial duration

func Retry

func Retry(
	ctx context.Context,
	attempt func(ctx context.Context) error,
	backoffDuration backoff.Func,
	failed func(err error),
) error
