Types

type Strategy

type Strategy func(attempts uint) time.Duration

Strategy is a function that provides the amount of time to wait before trying again. Note: attempts starts at 1

func BinaryExponential

func BinaryExponential(baseDelay time.Duration) Strategy

BinaryExponential returns an Exponential strategy with a base of 2.0

delay = baseDelay * 2^(attempts - 1) Ex. BinaryExponential(2*time.Seconds) = 2s, 4s, 8s, 16s, ...

func Constant

func Constant(interval time.Duration) Strategy

Constant returns a strategy that always returns the provided duration.

func Exponential

func Exponential(baseDelay time.Duration, base float64) Strategy

Exponential returns a strategy that exponentially increases based off of the number of attempts.

delay = baseDelay * base^(attempts - 1) Ex. Exponential(2*time.Seconds, 3) = 2s, 6s, 18s, 54s, ...

func Linear

func Linear(baseDelay time.Duration) Strategy

Linear returns a strategy that linearly increases based off of the number of attempts.

delay = baseDelay * attempts Ex. Linear(2*time.Seconds) = 2s, 4s, 6s, 8s, ...
