Crate subms_spsc_ring_buffer 

Wait-free SPSC ring buffer. Single producer, single consumer, bounded.

Sized to a power of two; index modulo is a bitmask, not a %. Head and tail counters live on their own cache lines (128-byte padding) to keep the producer’s writes from invalidating the consumer’s read line. Each side caches the opposite index and only re-reads through the atomic when its own cache says full / empty.

use subms_spsc_ring_buffer::SpscRingBuffer;

let (mut tx, mut rx) = SpscRingBuffer::with_capacity(64);
tx.try_push(42u32).unwrap();
assert_eq!(rx.try_pop(), Some(42));
assert_eq!(rx.try_pop(), None);

Structs

Consumer

Consumer handle. Move it to the consuming thread.

Producer

Producer handle. Move it to the producing thread; the type system enforces the SPSC invariant.

SpscRingBuffer

Constructor namespace. Use SpscRingBuffer::with_capacity.
