Struct Publisher 

pub struct Publisher<T: Copy> { /* private fields */ }

The write side of a Photon SPMC channel.

There is exactly one Publisher per channel. It is Send but not Sync — only one thread may publish at a time (single-producer guarantee enforced by &mut self).

Implementations

impl<T: Copy> Publisher<T>

pub fn publish(&mut self, value: T)

Publish a single value. Zero-allocation, O(1).

pub fn publish_batch(&mut self, values: &[T])

Publish a batch of values with a single cursor update.

Each slot is written atomically (seqlock), but the cursor advances only once at the end — consumers see the entire batch appear at once, and cache-line bouncing on the shared cursor is reduced to one store.

pub fn published(&self) -> u64

Number of messages published so far.

pub fn capacity(&self) -> u64

Ring capacity (power of two).
