Struct Backoff 

pub struct Backoff { /* private fields */ }

Exponential backoff starting at 500ms and capping at 30 seconds.

Each call to next_delay doubles the delay (with jitter) up to the configured maximum. Call reset after a successful connection to start over.

Implementations

impl Backoff

pub fn new() -> Self

Create a new backoff starting at 500ms, capping at 30s.

pub fn next_delay(&mut self) -> Duration

Get the next backoff duration and advance the state.

The delay is base_ms * 2^attempt, clamped to max_ms, with a small deterministic jitter derived from the attempt number.

pub fn reset(&mut self)

Reset the backoff to the initial value (call on successful connection).

pub fn current_ms(&self) -> u64

Get the current backoff duration in milliseconds (without advancing).

Trait Implementations

impl Default for Backoff

fn default() -> Self

Returns the “default value” for a type.
