Struct Consumer 

pub struct Consumer { /* private fields */ }

Sole-consumer handle on a SharedRingSpsc pair. Same Send + !Sync + !Clone shape as Producer, mirroring the SPSC contract on the read side.

Implementations

impl Consumer

pub fn try_pop(&self, out: &mut [u8]) -> Result<usize, RingError>

Pop one payload into out. Forwards to SpscRingCore::try_pop. The SPSC contract is type-system-enforced because there is exactly one Consumer in existence per pair (!Sync + !Clone).

pub fn capacity(&self) -> usize

Capacity of the underlying ring (always a power of 2).

pub fn tail(&self) -> u64

Current tail (consumer’s published position).
