Functions

func Do

func Do(count int, backoff Backoff, fn func() error) error

Types

type Backoff

type Backoff func(attempt int) time.Duration

Backoff defines a function that control the back-off duration between call retries.

func Exponential

func Exponential(interval time.Duration, base float64) Backoff

Exponential creates a Backoff that multiplies the interval by an exponentially increasing factor for each attempt.

func Fixed

func Fixed(interval time.Duration) Backoff

Fixed creates a Backoff with fixed interval between calls.

func Linear

func Linear(initial, interval time.Duration) Backoff

Linear creates a Backoff that linearly multiplies the interval by the attempt number for each attempt.

func Scheduled

func Scheduled(intervals ...time.Duration) Backoff

Scheduled creates a Backoff with scheduled periods of time between calls.

func (Backoff) WithJitter

func (b Backoff) WithJitter(jitter Jitter) Backoff

WithJitter creates a new Backoff with Jitter attached.

type Jitter

type Jitter func(d time.Duration) time.Duration

func Deviation

func Deviation(factor float64) Jitter
