Struct ExponentialBackoff 

pub struct ExponentialBackoff {
    pub initial: Duration,
    pub max: Duration,
    pub multiplier: f64,
    pub jitter: bool,
}

Exponential backoff configuration for retries

Computes delay as: min(initial * multiplier^attempt, max) with optional jitter.

Fields

initial: Duration

Initial backoff duration (default: 100ms)

max: Duration

Maximum backoff duration (default: 10s)

multiplier: f64

Backoff multiplier for exponential growth (default: 2.0)

jitter: bool

Enable jitter to prevent thundering herd (default: true)

When enabled, adds random delay of 0-25% to each backoff.

Implementations

impl ExponentialBackoff

pub fn new(initial: Duration, max: Duration) -> Self

Create backoff with custom initial and max durations

pub fn fast() -> Self

Create fast backoff for testing (1ms initial, 100ms max, no jitter)

pub fn aggressive() -> Self

Create aggressive backoff (50ms initial, 30s max)
