BroadcastProducer

Struct BroadcastProducer 

Source
pub struct BroadcastProducer { /* private fields */ }
Expand description

Manages tracks within a broadcast.

Insert tracks statically with Self::insert_track / Self::create_track, or handle on-demand requests via Self::dynamic.

Implementations§

Source§

impl BroadcastProducer

Source

pub fn new(info: Broadcast) -> Self

Create a producer for the given broadcast metadata. Prefer Broadcast::produce.

Source

pub fn insert_track(&mut self, track: TrackConsumer) -> Result<(), Error>

Insert a track into the lookup, returning an error on duplicate.

Stores a weak handle to the track. The caller (or the owner of the track’s TrackProducer) is responsible for keeping the track alive; when all producers are dropped, the entry becomes closed and is eventually evicted.

Source

pub fn remove_track(&mut self, name: &str) -> Result<(), Error>

Remove a track from the lookup.

Source

pub fn create_track(&mut self, track: Track) -> Result<TrackProducer, Error>

Produce a new track and insert it into the broadcast.

Source

pub fn unique_track(&mut self, suffix: &str) -> Result<TrackProducer, Error>

Create a track with a unique name using the given suffix.

Generates names like 0{suffix}, 1{suffix}, etc. and picks the first one not already used in this broadcast.

Source

pub fn dynamic(&self) -> BroadcastDynamic

Create a dynamic producer that handles on-demand track requests from consumers.

Source

pub fn consume(&self) -> BroadcastConsumer

Create a consumer that can subscribe to tracks in this broadcast.

Source

pub fn abort(&mut self, err: Error) -> Result<(), Error>

Abort the broadcast with the given error.

Externally-owned tracks are independent and must be aborted separately; inserted tracks are referenced via weak handles so that consumers can finish reading them. Pending dynamic track requests, however, are owned by the broadcast and have no other producer to fulfill them, so they are aborted here.

Source

pub fn is_clone(&self, other: &Self) -> bool

Return true if this is the same broadcast instance.
