pub struct Backoff {
    step: Cell<u32>,
}

Performs quadratic backoff in spin loops.

Fields

step: Cell<u32>

Implementations

impl Backoff

pub fn new() -> Self

Creates a new Backoff.

pub fn spin_light(&self)

Backs off using lightweight spinning.

This method should be used for retrying an operation because another thread made progress. i.e. on CAS failure.

pub fn spin_heavy(&self)

Backs off using heavyweight spinning.

This method should be used in blocking loops where parking the thread is not an option.
