Struct BackoffState 

pub struct BackoffState { /* private fields */ }

Per-instance mutable backoff state.

Carries the current interval and a lightweight pseudo-random seed so that no external RNG dependency is needed.

Implementations

impl BackoffState

pub fn new(seed: u32) -> Self

Create fresh state, seeded from the given value.

Use a per-peer value (e.g. truncated FaceId or timestamp) as the seed to decorrelate hellos across nodes.

pub fn next_failure(&mut self, cfg: &BackoffConfig) -> Duration

Compute the next wait duration and update internal state.

Call this after a failed probe to get the retry delay.

pub fn reset(&mut self, _cfg: &BackoffConfig)

Reset to the initial interval after a successful exchange.

Clears the current interval so the next [next_failure] call starts fresh from cfg.initial_interval.

pub fn current(&self) -> Duration

Current interval without modification (peek).
