Functions

func Run

func Run(initialInterval float64, maxInterval float64, numTries uint, function RetryableFunc) error

Run retries a function up to numTries times with exponential backoff. If numTries == 0, retry indefinitely. If interval == 0, Retry will not delay retrying and there will be no exponential backoff. If maxInterval == 0, maxInterval is set to +Infinity. Intervals are in seconds. Returns an error if initial > max intervals, if retries are exhausted, or if the passed function returns an error.

Types

type RetryableFunc

type RetryableFunc func(uint) (bool, error)

RetryableFunc performs an action and returns a bool indicating whether the function is done, or if it should keep retrying, and an error which will abort the retry and be returned by the Retry function. The 0-indexed attempt is passed with each call.
