Struct Producer 

pub struct Producer { /* private fields */ }

Sole-producer handle on a SharedRingSpsc pair. Send so it can be moved to a producer thread; !Sync so it cannot be shared across threads (which would violate the SPSC contract). Not Clone: a second producer is statically impossible.

Implementations

impl Producer

pub fn try_push(&self, payload: &[u8]) -> Result<(), RingError>

Push one payload. Forwards to SpscRingCore::try_push. The SPSC contract is type-system-enforced because there is exactly one Producer in existence per pair (!Sync + !Clone).

pub fn capacity(&self) -> usize

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

pub fn head(&self) -> u64

Current head (producer’s published position).
