Types

type Func

type Func func() time.Duration

when an operation is reasonably expected to fail at times and retry attempts should be done, this function should be called after each attempt to get the new duration before the next attempt should be tried.

usual implementations are expected to return different duration for each call, like [0ms, 100ms, 200ms, 400ms, ...]

func ExponentialWithCappedMax

func ExponentialWithCappedMax(base time.Duration, max time.Duration) Func

given (100ms, 1s) => [0ms, 100ms, 200ms, 400ms, 800ms, 1s, 1s, 1s, ...]

func Fixed

func Fixed(dur time.Duration) Func

uses a fixed duration for backoff (always returns e.g. 1s, 1s, ...)
