Types

type ExponentialBackoffConfig

type ExponentialBackoffConfig struct {
	Base       time.Duration
	Cap        time.Duration
	Multiplier float64
}

ExponentialBackoffConfig is the configuration for exponential backoff.

type Func

type Func func(attempts int, resp *http.Response) time.Duration

Func generates backoff delays.

func ExponentialBackoff

func ExponentialBackoff(cfg ExponentialBackoffConfig) Func

ExponentialBackoff returns an exponential backoff with partial jitter.

func RateLimitedExponentialBackoff

func RateLimitedExponentialBackoff(cfg ExponentialBackoffConfig) Func

RateLimitedExponentialBackoff returns an backoff function that prioritizes `Retry-After` headers, defaulting to exponential backoff if they're not found. Adds partial jitter.
