Struct WakeNotifierProcessor 

pub struct WakeNotifierProcessor { /* private fields */ }

Fires a WakeNotifier when a frame of one of the watched FrameKinds satisfies a predicate, then forwards the frame unchanged. Port of pipecat WakeNotifierFilter — used to wake another component (e.g. arm the brain on the first user-stopped-speaking) without consuming the frame.

Implementations

impl WakeNotifierProcessor

pub fn new( kinds: Vec<FrameKind>, predicate: WakePredicate, notifier: WakeNotifier, ) -> Self

Watch kinds; when one matches predicate, call notifier.

Trait Implementations

impl FrameProcessor for WakeNotifierProcessor

fn name(&self) -> &str

Stable, human-readable name (observer events, error attribution, tracing).

fn process_frame<'life0, 'life1, 'async_trait>( &'life0 mut self, env: Envelope, link: &'life1 Link, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle one frame. Push results via link. Must not block: long work (a provider round-trip) is driven by an internally-spawned task that feeds results back as frames. The default impl forwards the frame unchanged in its direction — so a pure observer/no-op processor is process_frame = default.

fn start<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _setup: &'life1 ProcessorSetup, _params: &'life2 StartParams, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called once when the Frame::Start frame reaches this processor, before any data frame. Open sockets / spawn provider readers here. Default: no-op.

fn stop<'life0, 'async_trait>( &'life0 mut self, _reason: StopReason, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Called on End/Stop/Cancel after the terminal frame is forwarded. Flush + close. Default: no-op.

fn can_generate_metrics(&self) -> bool

Whether this processor produces metrics (pipecat can_generate_metrics, :395). Services override to true.
