Struct RenderCore 

pub struct RenderCore { /* private fields */ }

Render core holding device, surface, pipelines, and frame resources.

Implementations

impl RenderCore

pub fn read_offscreen_rgba(&self) -> Result<Vec<u8>, OffscreenReadbackError>

Reads the last offscreen-rendered frame back as tightly packed RGBA8 pixels in row-major order with a top-left origin.

The returned buffer has width * height * 4 bytes and no row padding. RGBA8 presentation bytes are sRGB-encoded even when the output texture uses a non-sRGB format, matching PNG and most image consumers.

impl RenderCore

pub fn resources(&self) -> RenderResources<'_>

Returns shared GPU resources used for pipeline creation.

pub fn window(&self) -> &Window

Returns the current window handle.

Panics if this core was created for offscreen rendering; check RenderCore::has_surface first.

pub fn window_arc(&self) -> Arc<Window>

Returns a cloned window handle for external storage.

Panics if this core was created for offscreen rendering.

pub fn has_surface(&self) -> bool

Returns whether this core renders into a window surface.

Offscreen cores return false.

pub fn device(&self) -> &Device

Returns the WGPU device.

pub fn queue(&self) -> &Queue

Returns the WGPU queue.

pub fn surface_config(&self) -> &SurfaceConfiguration

Returns the current surface configuration.

pub fn pipeline_cache(&self) -> Option<&PipelineCache>

Returns the pipeline cache if available.

pub fn sample_count(&self) -> u32

Returns the configured MSAA sample count.

pub fn register_draw_pipeline<T, P>(&mut self, pipeline: P)

where T: DrawCommand + 'static, P: DrawablePipeline<T> + 'static,

Registers a new drawable pipeline for a specific command type.

pub fn register_compute_pipeline<T, P>(&mut self, pipeline: P)

where T: ComputeCommand + 'static, P: ComputablePipeline<T> + 'static,

Registers a new compute pipeline for a specific command type.
