Expand description

Stores the value at the specified memory location, returning the old value. `T` must be an integer or pointer type.

The stabilized version of this intrinsic is available on the `atomic` types via the `swap` method by passing `Ordering::AcqRel` as the `order`. For example, `AtomicBool::swap`.
