Struct AuditPipeline 

pub struct AuditPipeline { /* private fields */ }

Bridges engine lifecycle hooks to an AuditSink over a bounded channel.

Implementations

impl AuditPipeline

pub fn new(sink: Arc<dyn AuditSink>, capacity: usize) -> Self

Spawn the background writer draining into sink, buffering up to capacity records.

pub fn dropped(&self) -> u64

Count of records dropped because the channel was full.

Trait Implementations

impl Observer for AuditPipeline

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_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.

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.
