Struct FinalizeProcessor 

pub struct FinalizeProcessor<S: SessionSource> { /* private fields */ }

On terminal End (the stop hook), runs the LiveState/finalize artifact-upload + SessionSource::complete logic verbatim from call.rs (render recording + transcript, upload via presigned URL, persist the stored keys, fold disposition into collected_vars, write the run result). Generic over SessionSource.

Trait Implementations

impl<S: SessionSource + 'static> FrameProcessor for FinalizeProcessor<S>

fn name(&self) -> &str

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

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 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 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 can_generate_metrics(&self) -> bool

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