Enum ExportOp 

#[non_exhaustive]
pub enum ExportOp {
    EmitFrame(VideoFrame),
    EmitAudio(Vec<f32>),
    Raw {
        format: &'static str,
        payload: Vec<u8>,
    },
    EmitText(TextRun),
}

Output action at render time.

A crate::render::SceneSampler emits one or more of these per sampled timestamp. Raster exports typically see a single EmitFrame; vector exports (PDF) see a sequence of structured drawing operations so the structural content survives.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmitFrame(VideoFrame)

Send a decoded video frame to the output.

EmitAudio(Vec<f32>)

Send a block of audio samples. Interleaved F32, scene-bus rate.

Raw

Raw format-specific output — the exporter gives this meaning. PDF exporters stuff PDF operators in here (Tj glyph shows, Do image draws, RG/f/S colour + fill/stroke).

Fields

format: &'static str

payload: Vec<u8>

EmitText(TextRun)

Emit a structured text run (font / glyph / position) so the downstream exporter can write selectable text instead of a rasterised glyph bitmap.
