Function atomic_umin
unsafe fn atomic_umin<T: Copy, ORD: AtomicOrdering>(dst: *mut T, src: T) -> T
Minimum with the current value using an unsigned comparison.
T must be an unsigned integer type.
The stabilized version of this intrinsic is available on the
atomic unsigned integer types via the fetch_min method. For example, AtomicU32::fetch_min.
