🔬 This is a nightly-only experimental API. (core_intrinsics)
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
atomic types via the compare_exchange_weak method by passing
Ordering::Acquire as both the success and failure parameters.
For example, AtomicBool::compare_exchange_weak.
