Implementations

impl RetryStrategy

pub fn delay_for_attempt(&self, attempt: u32) -> Option<Duration>

Returns None if no more retries should be attempted

pub fn max_retries(&self) -> u32

Get maximum number of retries

pub fn fixed(max_retries: u32, delay: Duration) -> Self

Create a fixed retry strategy

pub fn exponential(max_retries: u32, initial_delay: Duration) -> Self

Create an exponential backoff strategy

pub fn linear( max_retries: u32, initial_delay: Duration, increment: Duration, ) -> Self

Create a linear backoff strategy
