A macro to define a statically allocated AtomicRef<'static, T> which is initialized to None.

Examples

use std::sync::atomic::Ordering;

static_atomic_ref! {
    static SOME_REFERENCE: AtomicRef<i32>;
    pub static PUB_REFERENCE: AtomicRef<u64>;
}

fn main() {
    let a: Option<&'static i32> = SOME_REFERENCE.load(Ordering::SeqCst);
    assert_eq!(a, None);
}
