retry

Simple library for retry mechanism. Context allow to set context of retry default are Background context. Return the direct last error that came from the retried function default is false (return wrapped errors with everything) WithTimer provides a way to swap out timer module implementations. This primarily is useful for mocking/testing, where you may not want to explicitly wait for a set duration for retries. DelayTypeFunc is called to return the next delay to wait after the retriable function fails on err after n attempts. FixedDelay is a DelayType that keeps delay the same through all iterations. DelayTypeFunc accepts a new parameter err - this breaking change affects only your custom Delay Functions. RetryIf controls whether a retry should be attempted after an error (assuming there are any retry attempts remaining).
