Struct BackoffBuilder 

pub struct BackoffBuilder { /* private fields */ }

Builder for Backoff.

Implementations

impl BackoffBuilder

pub fn initial(self, d: Duration) -> Self

Initial delay. Default: 100ms.

pub fn max_delay(self, d: Duration) -> Self

Maximum delay cap. Default: 30s.

pub fn max_retries(self, n: u32) -> Self

Maximum number of retries. Default: unlimited.

pub fn deadline(self, deadline: Instant) -> Self

Wall-clock deadline. After this instant, Backoff::wait returns Err(Exhausted). Sleep durations are capped to not exceed it.

Default: no deadline.

pub fn jitter(self, factor: f64) -> Self

Jitter factor (0.0 to 1.0). Default: 0.0 (no jitter).

Each delay is randomly scaled by 1.0 ± jitter. For example, jitter(0.25) means a 100ms delay becomes 75ms–125ms.

pub fn build(self) -> Backoff

Build the backoff.

Panics

Panics if initial exceeds max_delay.

fn default() -> Self

Returns the “default value” for a type.
