Struct FrameMeta 

pub struct FrameMeta {
    pub id: u64,
    pub name: &'static str,
    pub pts: Option<i64>,
    pub broadcast_sibling_id: Option<u64>,
    pub extra: Option<Arc<Map<String, Value>>>,
    pub transport_source: Option<Arc<str>>,
    pub transport_destination: Option<Arc<str>>,
}

Per-frame metadata, carried out of band in the channel Envelope so the hot enum variant (OutputAudio(Arc<AudioFrame>)) stays a thin pointer move (PROCESSOR-DESIGN §1.1). Mirrors the pipecat Frame base fields (frames.py:73-79). Cheap to clone (the extra map is Arced).

Fields

id: u64

Process-unique monotonic id (see next_frame_id).

name: &'static str

Human name for tracing/observers, e.g. “OutputAudio”. Built lazily.

pts: Option<i64>

Presentation timestamp in nanoseconds on the pipeline clock, if set.

broadcast_sibling_id: Option<u64>

Paired id when a frame was broadcast both directions (frames.py:76).

extra: Option<Arc<Map<String, Value>>>

Arbitrary sideband metadata (Arc so cloning a frame is cheap).

transport_source: Option<Arc<str>>

Transport source/destination track names (frames.py:78-79).

transport_destination: Option<Arc<str>>

Implementations

impl FrameMeta

pub fn new(frame: &Frame) -> Self

A fresh meta for frame with a new monotonic id and the frame’s static name. The common path for producing a frame inside a processor.

Trait Implementations

impl Clone for FrameMeta

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameMeta

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

Formats the value using the given formatter.
