Struct PixelsRenderer 

pub struct PixelsRenderer { /* private fields */ }

Implementations

impl PixelsRenderer

pub fn new() -> Self

pub fn draw(&self, frame: &mut [u8], width: u32, height: u32)

pub fn draw_scaled(&self, frame: &mut [u8], width: u32, height: u32, scale: f32)

Rasterizes logical scene coordinates at scale device pixels per point. Hit regions stay in logical coordinates. Invalid scales use 1.0.

Trait Implementations

impl Default for PixelsRenderer

fn default() -> Self

Returns the “default value” for a type.

impl Renderer for PixelsRenderer

type Scene = Scene

type Error = PixelsRendererError

fn attach_app_context_services(&mut self, app_context: &AppContext)

Installs renderer-provided app services into the target AppContext.

fn scene(&self) -> &Self::Scene

fn scene_mut(&mut self) -> &mut Self::Scene

fn rebuild_scene( &mut self, layout_tree: &LayoutTree, _viewport: Size, ) -> Result<(), Self::Error>

fn rebuild_scene_from_applier( &mut self, applier: &mut MemoryApplier, root: NodeId, _viewport: Size, ) -> Result<(), Self::Error>

Rebuilds the scene by traversing the LayoutNode tree directly via Applier.

fn update_scene_from_applier( &mut self, applier: &mut MemoryApplier, root: NodeId, _viewport: Size, updates: SceneUpdates<'_>, ) -> Result<(), Self::Error>

fn update_visual_scene_from_applier( &mut self, applier: &mut MemoryApplier, root: NodeId, _viewport: Size, updates: SceneUpdates<'_>, ) -> Result<(), Self::Error>

fn set_root_scale(&mut self, _scale: f32)

Sets how many device pixels the renderer draws for one logical unit.

fn draw_dev_overlay(&mut self, _text: &str, _viewport: Size)

Draw a development overlay (e.g., FPS counter) on top of the scene.

fn set_inspector_overlay(&mut self, _graph: Option<RenderGraph>)

Replaces the developer inspector graph outside the application scene.

fn needs_frame_warmup(&self) -> bool

Returns whether renderer-side cache materialization needs a visible follow-up frame.

fn awaits_pipelines(&self) -> bool

Returns whether the last frame drew a placeholder for an effect whose pipelines are still compiling, so its picture is not final yet; the renderer asks for the frame that replaces it once they land.
