Types ¶

type Backoff ¶

type Backoff interface {
	// Delay returns mapping of i to Delay.
	Delay(i int) time.Duration
}

Backoff is the interface that contains logic of delaying operation retry.

type Type ¶

type Type uint8

Type reports how to Backoff operation

const (
	TypeNoBackoff Type = 1 << iota >> 1

	TypeFast
	TypeSlow

	TypeAny = TypeFast | TypeSlow
)
