Constants

const NoiseDelayMs = 1000 // Each delay has random additional milliseconds.

Variables

var Backoff5Min = NewBackoff(time.Second, 5*time.Minute, 2.0)

Backoff5Min goes from 1 second to 5 minutes with each delay is twice bigger.

Types

type Backoff

type Backoff struct {
	// contains filtered or unexported fields
}

func NewBackoff

func NewBackoff(initial time.Duration, max time.Duration, factor float64) *Backoff

func (Backoff) Delay

func (b Backoff) Delay(retries int) time.Duration

Delay returns delay distributed from initial to max.
