intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Stores a value if the current value is the same as the old
value.
The stabilized version of this intrinsic is available on the
std::sync::atomic
types via the compare_exchange_weak
method by passing
Ordering::SeqCst
as the success
and
Ordering::Acquire
as the failure
parameters. For example,
AtomicBool::compare_exchange_weak
.
