Struct NoopObserver 

pub struct NoopObserver;

The default observer. Selected automatically when the builder gets none.

Trait Implementations

impl Clone for NoopObserver

fn clone(&self) -> NoopObserver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoopObserver

impl Debug for NoopObserver

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NoopObserver

fn default() -> NoopObserver

Returns the “default value” for a type.

impl Observer for NoopObserver

fn on_event(&self, _event: &StreamEvent)

A stream lifecycle event was emitted.

fn on_publish_started(&self, _app: &str)

A publish session started in application app.

fn on_publish_ended(&self, _app: &str)

A publish session ended in application app.

fn on_frame(&self, _key: &StreamKey, _frame: &MediaFrame)

A frame was published. Hot-path hook — keep it cheap. The default is a no-op so the branch is trivially predicted away when no observer is installed.

fn on_subscriber_lagged(&self, _key: &StreamKey, _skipped: u64)

A subscriber fell behind the broadcast buffer and skipped frames were dropped from its view before it could read them. This is the canonical slow-consumer signal: alert on it. Fired by StreamHandle::subscribe_resilient.

fn on_subscriber_evicted(&self, _key: &StreamKey)

A chronically slow subscriber crossed its max_lag budget and was shed. Fired by Subscription::recv.

fn on_rate_limited(&self, _key: &StreamKey)

An ingress rate limit was exceeded for key; the protocol handler should drop or backpressure the connection. Handlers call this from their ingest loop (e.g. when IngestRateLimit returns false).

fn on_stream_reaped(&self, _key: &StreamKey)

A publish session was reaped for exceeding the engine’s idle timeout.
