🔬This is a nightly-only experimental API. (
core_intrinsics
)Expand description
Stores a value if the current value is the same as the old
value.
The stabilized version of this intrinsic is available on the
atomic
types via the compare_exchange_weak
method by passing
Ordering::Release
and Ordering::SeqCst
as the success and failure parameters.
For example, AtomicBool::compare_exchange_weak
.
