Struct Producer 

pub struct Producer { /* private fields */ }

Publishes a binary value over a track, one value per group.

Each update rolls a new group holding the whole value, so a consumer only ever needs the newest group and older ones are dropped. For a log where every payload survives, use stream instead.

Cheaply clonable: clones share one underlying track, like other MoQ producers.

Implementations

impl Producer

pub fn new(track: Producer, config: Config) -> Self

Create a producer that publishes to the given track.

pub fn consume(&self) -> Subscriber

Create a subscriber for the underlying track.

pub fn is_used(&self) -> bool

Whether any consumer for the underlying track currently exists.

The demand signal for a producer serving on request: an unused track is cached state nobody is watching, safe to drop and recreate on the next request.

pub fn update(&mut self, payload: impl Into<Timed<Bytes>>) -> Result<usize>

Publish a new value, superseding the previous one, and return the frame’s encoded size.

Unlike moq-json, an identical value is republished rather than skipped: comparing two opaque blobs costs a full scan, and only the caller knows whether its bytes changed.

pub fn finish(&mut self) -> Result<()>

Finish the track.

Trait Implementations

impl Clone for Producer

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
