Struct AdaptedSource 

pub struct AdaptedSource<S: SceneSource> { /* private fields */ }

Source wrapper that converts every emitted frame to a target pixel format.

Overrides the reported SourceFormat so the downstream sink’s init() sees the adapted canvas, not the scene’s native one. Cheap when the formats already match (the adapter short-circuits in adapt_frame_to).

Implementations

impl<S: SceneSource> AdaptedSource<S>

pub fn new(inner: S, target: PixelFormat) -> Self

Wrap inner, converting every pulled frame to target. Use this when a sink accepts a specific pixel format that differs from the scene’s canvas (e.g. RGB24 for a JPEG writer while the scene composes in YUV420P).

pub fn inner(&self) -> &S

Access the wrapped source.

pub fn inner_mut(&mut self) -> &mut S

Mutable access to the wrapped source — useful for the streaming-compositor pattern where the caller mutates scene state between pulls.

fn format(&self) -> SourceFormat

Declared format. Constant across a session.

fn pull(&mut self) -> Result<Option<RenderedFrame>>

Produce the next rendered tick. Returns Ok(None) when the source is exhausted (finite scene reached its end). For indefinite sources, this never returns None.
