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

Stores the value at the specified memory location, returning the old value.

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