Struct SourceFormat 

pub struct SourceFormat {
    pub canvas: Canvas,
    pub framerate: Rational,
    pub time_base: TimeBase,
    pub sample_rate: u32,
    pub duration: SceneDuration,
    pub paged: bool,
}

Format contract between a SceneSource and a SceneSink.

Everything a sink needs to set up encoders / muxers / windows before the first frame arrives.

Fields

canvas: Canvas

framerate: Rational

time_base: TimeBase

sample_rate: u32

duration: SceneDuration

Whether the source has a known end. Finite(n) lets sinks size output containers; Indefinite signals a streaming source that runs until externally stopped.

paged: bool

Pages-mode flag — true when the source scene carries a non-empty Scene::pages list. Lets paged-content sinks (PDF, multi-page TIFF) reject timeline scenes early in init(), and lets video sinks reject paged scenes.

Implementations

impl SourceFormat

pub fn from_scene(scene: &Scene) -> Self

Build from a scene’s current state. The renderer consumes this at init() time so downstream encoder settings match the scene’s declarations.

Trait Implementations

impl Clone for SourceFormat

fn clone(&self) -> SourceFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceFormat

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

Formats the value using the given formatter.
