Function atomic_xadd_acqrel

pub unsafe fn atomic_xadd_acqrel<T: Copy>(_dst: *mut T, _src: T) -> T

🔬This is a nightly-only experimental API. (core_intrinsics)

Adds to the current value, returning the previous value.

The stabilized version of this intrinsic is available on the atomic types via the fetch_add method by passing Ordering::AcqRel as the order. For example, AtomicIsize::fetch_add.
