Struct tower::retry::backoff::ExponentialBackoff

pub struct ExponentialBackoff<R = HasherRng> { /* private fields */ }

A jittered exponential backoff strategy.

The backoff duration will increase exponentially for every subsequent backoff, up to a maximum duration. A small amount of random jitter is added to each backoff duration, in order to avoid retry spikes.

Trait Implementations

impl<R> Backoff for ExponentialBackoff<R>

where R: Rng,

type Future = Sleep

The future associated with each backoff. This usually will be some sort of timer.

fn next_backoff(&mut self) -> Self::Future

Initiate the next backoff in the sequence.

impl<R: Clone> Clone for ExponentialBackoff<R>

fn clone(&self) -> ExponentialBackoff<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Debug> Debug for ExponentialBackoff<R>

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

Formats the value using the given formatter.
