Module atomic_utilities::fence_rmw

This mod provides orderings to use with RMW operations that optimally handle the case when all loads and stores after an RMW operation must be ordered after the operation.

Example:

use std::sync::atomic::{AtomicUsize, fence, Ordering};
use atomic_utilities::fence_rmw::{RMWOrder, fence_rmw};

let atomic_refcnt = AtomicUsize::new(0);
atomic_refcnt.fetch_add(1, RMWOrder);

// ... do work here
// This will be ordered after the store of the fetch_add
// and will use minimal fences for various hardware platforms
atomic_refcnt.fetch_sub(1, Ordering::Release);

Constants

RMWOrder

The ordering to be used for RMW operations in this fencing scheme

Functions

fence_rmw

The fence to be used after the RMW
