Trait utils_atomics::traits::AtomicSub

pub trait AtomicSub<T = <Self as Atomic>::Primitive>: Atomic {
    // Required method
    fn fetch_sub(&self, val: T, order: Ordering) -> Self::Primitive;
}

A trait representing atomic types that support subtraction operations.

Required Methods

fn fetch_sub(&self, val: T, order: Ordering) -> Self::Primitive

Subtracts from the current value, returning the previous value.

This operation wraps around on overflow.

fetch_sub takes an Ordering argument which describes the memory ordering of this operation. All ordering modes are possible. Note that using Acquire makes the store part of this operation Relaxed, and using Release makes the load part Relaxed.

Object Safety

This trait is not object safe.
