Trait AtomicMin

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

A trait representing atomic types that support minimum operations.

Required Methods

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

Minimum with the current value.

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

Returns the previous value.

fetch_min 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
