intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

[]

Stores the value at the specified memory location, returning the old value. The stabilized version of this intrinsic is available on the std::sync::atomic types via the swap method by passing Ordering::AcqRel as the order. For example, AtomicBool::swap.
