Examples

use owned_pin::sync::{RefCount, RefCounted, arsc_init_on_stack};

#[derive(RefCounted)]
struct Large {
    x: [u64; 100],
    #[count_on]
    rc: RefCount,
}

// This value is directly written to the target place,
// instead of being temporarily placed on the stack.
arsc_init_on_stack!(let l = Large {
    x <- [0; 100],
    rc: RefCount::new(),
});
assert_eq!(l.x, [0; 100]);
