Struct ExponentialBackoff 

pub struct ExponentialBackoff {
    pub start: Duration,
    pub factor: f64,
    pub max_duration: Option<Duration>,
    pub max_retries: Option<usize>,
}

A RetryPolicy which backs off exponentially

Fields

start: Duration

The start of the backoff

factor: f64

The factor of which to backoff by

max_duration: Option<Duration>

The maximum duration to delay

max_retries: Option<usize>

The maximum number of retries before giving up

Implementations

impl ExponentialBackoff

pub const fn new( start: Duration, factor: f64, max_duration: Option<Duration>, max_retries: Option<usize>, ) -> Self

Create a new exponential backoff retry policy

Trait Implementations

impl Clone for ExponentialBackoff

fn clone(&self) -> ExponentialBackoff

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExponentialBackoff

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl RetryPolicy for ExponentialBackoff

fn retry( &self, _error: &Error, last_retry: Option<(usize, Duration)>, ) -> Option<Duration>

Submit a new retry delay based on the Error, last retry number and duration, if available. A policy may also return None if it does not want to retry

fn set_reconnection_time(&mut self, duration: Duration)

Set a new reconnection time if received from an event
