Struct Backoff 

pub struct Backoff { /* private fields */ }

Exponential backoff with a configurable cap.

Each call to next_delay doubles the delay (starting from initial_delay_secs) up to max_delay_secs. Calling reset returns to the initial delay.

This is fully deterministic — no timers or randomness.

Implementations

impl Backoff

pub fn new(initial_delay_secs: u64, max_delay_secs: u64) -> Self

Create a new backoff starting at initial_delay_secs, capped at max_delay_secs.

pub fn next_delay(&mut self) -> u64

Return the next delay and advance the backoff.

pub fn reset(&mut self)

Reset backoff to the initial delay.
