Functions

func WithRetryBackoff

func WithRetryBackoff(ctx context.Context, maxRetryTimes uint, firstDuration time.Duration, f func(uint) bool)

WithRetryBackoff provides a general retry logic.

The given f will keep running, until: - f returns true. It means work is done. - retry times is greater than the given times - ctx is done.

Otherwise, this function will wait a time of the given duration in a backoff way, and continue to execute f.

The argument provided for f is the retried times.
