Struct ExponentialBackoff

pub struct ExponentialBackoff { /* private fields */ }

Exponential backoff strategy with optional jitter

This strategy increases the delay exponentially with each attempt, and can add random jitter to prevent multiple retries from synchronizing.

Implementations

impl ExponentialBackoff

pub fn new() -> Self

Create a new exponential backoff with default settings

Defaults:

• Initial delay: 100ms
• Max delay: 30000ms (30 seconds)
• Factor: 2.0 (doubles with each attempt)
• Jitter: false

pub fn with_initial_delay(self, delay_ms: u64) -> Self

Set the initial delay in milliseconds

pub fn with_max_delay(self, delay_ms: u64) -> Self

Set the maximum delay in milliseconds

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

Set the multiplication factor for each attempt

pub fn with_jitter(self, jitter: bool) -> Self

Enable or disable jitter
