Struct RenderBackend 

pub struct RenderBackend<'w> { /* private fields */ }

Low-level wgpu backend that owns surface, pipeline, and GPU buffers.

Implementations

impl<'w> RenderBackend<'w>

pub async fn to_canvas( _canvas: HtmlCanvasElement, _config: RenderConfig, ) -> Result<Self, Error>

pub async fn to_canvas_with_context( _canvas: HtmlCanvasElement, _config: RenderConfig, _shared_context: Option<SharedGpuContext>, ) -> Result<(Self, SharedGpuContext), Error>

pub async fn new( surface: Surface<'w>, instance: Instance, config: RenderConfig, ) -> Result<Self, Error>

pub fn get_clip_depth(&mut self) -> u32

Current stencil clip depth.

pub fn resize(&mut self, width: u32, height: u32)

Resize both the physical surface and logical viewport.

pub fn resize_surface(&mut self, width: u32, height: u32)

Resize the backing surface, clamping to device limits.

pub fn set_viewport(&mut self, width: f32, height: f32, dpr: [f32; 2])

Update logical viewport uniforms without reallocating the surface.

pub fn max_surface_dimension(&self) -> u32

Maximum texture dimension supported by the active adapter.
