impl Copy for CpuRenderer

impl Debug for CpuRenderer

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

Formats the value using the given formatter.

Returns the “default value” for a type.

impl Renderer for CpuRenderer

fn render_frame(&self, atlas: &SpriteAtlas, frame_index: u32) -> Result<Vec<u8>>

Extracts frame frame_index as frame_width * frame_height * 4 RGBA8 bytes.

fn compose( &self, layers: &[(&SpriteAtlas, u32, i32, i32)], width: u32, height: u32, ) -> Result<Vec<u8>>

Composites layers — (atlas, frame_index, x, y) — onto a transparent width×height canvas (src-over alpha blending), returning width * height * 4 RGBA8 bytes. Layers are painted in order (later = on top); out-of-canvas pixels are clipped.
