Struct AcceptBackoff 

pub struct AcceptBackoff { /* private fields */ }

Exponential backoff state for listener.accept() retry loops.

Accept errors (typically EMFILE/ENFILE when the process has run out of file descriptors, or transient ConnectionAborted under load) are not fatal to the listener. Servers should log, sleep, and re-poll. Use AcceptBackoff to keep the sleep schedule consistent across transports without duplicating the constants in every serve_* implementation.

Implementations

impl AcceptBackoff

pub const fn new() -> AcceptBackoff

Construct with the default 5 ms → 1 s schedule.

pub fn reset(&mut self)

Reset the schedule after a successful accept.

pub async fn sleep_and_grow(&mut self)

Sleep for the current backoff and double it (capped at max). Use the tokio sleep so this is cooperative on the runtime that runs the accept loop.

pub fn current_and_grow(&mut self) -> Duration

Returns the current backoff duration and doubles the internal counter (capped at max). Use this when you need to drive the sleep with a non-tokio timer (e.g. compio::time::sleep).
