Struct Backoff

pub struct Backoff<'a> { /* private fields */ }

An object to yield execution of an async task while in a spin loop.

This is useful when waiting for some condition (such as a device register to change states) that can only be polled and does not have an interrupt-based notification.

Implementations

impl<'a> Backoff<'a>

pub fn new(driver: &'a dyn Driver) -> Self

Returns a new backoff object, usable for the lifetime of one spin loop.

pub async fn back_off(&mut self)

Yields execution.

Initially just yields to any other pending tasks. Yields for longer the more times this is called.
