Functions

func Parse

func Parse(retryAfter string, fallback time.Duration) time.Duration

Parse parses the backoff time specified in the Retry-After header if present. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Retry-After.

The second parameter is the fallback duration to use if the header is not present or invalid.

Example:

time.Sleep(retryafter.Parse(resp.Header.Get("Retry-After"), 5*time.Second))

func Should

func Should(statusCode int, retryOnRateLimit bool) bool

Should returns true if the given status code indicates that the request should be retried.

if retryafter.Should(resp.StatusCode, true) {
	time.Sleep(retryafter.Parse(resp.Header.Get("Retry-After"), 5*time.Second))
}
