pub unsafe fn atomic_cxchg_acqrel_seqcst<T: Copy>(
dst: *mut T,
old: T,
src: T,
) -> (T, bool)🔬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.
T must be an integer or pointer type.
The stabilized version of this intrinsic is available on the
atomic types via the compare_exchange method by passing
Ordering::AcqRel and Ordering::SeqCst as the success and failure parameters.
For example, AtomicBool::compare_exchange.
