🔬This is a nightly-only experimental API. (core_intrinsics)

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.
