func Do(ctx context.Context, fn func(context.Context) (bool, error), opts ...Option) error

Do an action with exponential randomized backoff.

type OnRetry func(attempt float64, err error)

type Option func(*retrier)

An Option changes the default behavior of a retrier.

func UseBaseSleep(base time.Duration) Option

UseBaseSleep makes the retrier sleep at least `base`.

func UseCapSleep(cap time.Duration) Option

UseCapSleep makes the retrier sleep at most `cap`.

func UseFactor(factor float64) Option

UseFactor makes the retrier grow its exponential backoff using factor as the base of the exponent.

func UseLog(log OnRetry) Option

UseLog makes the retrier log retries to the given func.

func UseRand(rd *rand.Rand) Option

UseRand makes the retrier use the *rand.Rand for randomization of retries.
