pub unsafe fn atomic_cxchg<T, const ORD_SUCC: AtomicOrdering, const ORD_FAIL: AtomicOrdering>(
dst: *mut T,

T: Copy,
core_intrinsics)
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. For example, AtomicBool::compare_exchange.
