atomic_enum

An attribute to create an atomic wrapper around a C-style enum.

Internally, the generated wrapper uses an AtomicUsize to store the value. The atomic operations have the same semantics as the equivalent operations of AtomicUsize.

Example

#[atomic_enum]
#[derive(PartialEq)]
enum CatState {
    Dead = 0,
    BothDeadAndAlive,
    Alive,
}

let state = AtomicCatState::new(CatState::Dead);
state.store(CatState::Alive, Ordering::Relaxed);
assert_eq!(state.load(Ordering::Relaxed), CatState::Alive);

This attribute does not use or generate any unsafe code.

The crate can be used in a #[no_std] environment.
