Crate subms_mpsc_queue 

Vyukov-style multi-producer single-consumer linked queue.

Producers enqueue with one swap on the tail; the consumer drains by following next pointers from the head. The dangling-tail window is the load-bearing detail: between the producer’s CAS-of-tail and the prev.next = new link, the consumer can see next == null while there is actually a publisher in flight. MpscQueue::try_pop returns PopResult::Inconsistent in that window so the caller can spin or back off rather than treating it as empty.

use subms_mpsc_queue::{MpscQueue, PopResult};
let mut q: MpscQueue<u32> = MpscQueue::new();
q.push(7);
q.push(8);
assert!(matches!(q.try_pop(), PopResult::Some(7)));
assert!(matches!(q.try_pop(), PopResult::Some(8)));
