Trait utils_atomics::traits::AtomicMax

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

A trait representing atomic types that support maximum operations.

Required Methods

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

Maximum with the current value.

Finds the maximum of the current value and the argument val, and sets the new value to the result.

Returns the previous value.

fetch_max 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.
