pub unsafe fn atomic_xchg_seqcst<T: Copy>(dst: *mut T, src: T) -> T🔬This is a nightly-only experimental API. (
core_intrinsics)Expand description
Stores the value at the specified memory location, returning 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 swap method by passing
Ordering::SeqCst as the order. For example, AtomicBool::swap.
