Struct SdfPipelineStore 

pub struct SdfPipelineStore { /* private fields */ }

Manages cached SDF pipelines and renders SDF commands.

Implementations

impl SdfPipelineStore

pub fn new(gpu: &GpuContext) -> Self

Create a new SDF pipeline store.

pub fn new_headless(device: &Device, format: TextureFormat) -> Self

Create for headless testing (no surface required).

pub fn prepare(&self, queue: &Queue, camera: &Camera2D, time: f32)

Update the camera and time uniforms. Call once per frame before rendering.

pub fn set_time(&self, queue: &Queue, time: f32)

Update the time uniform. Call once per frame before rendering.

pub fn get_or_create_pipeline( &mut self, device: &Device, sdf_expr: &str, fill: &SdfFill, ) -> u64

Get or create the render pipeline for the given SDF expression + fill. Returns a reference to the cached pipeline.

pub fn camera_bind_group_layout(&self) -> &BindGroupLayout

Return the camera bind group layout for sharing with the sprite pipeline.

pub fn render( &mut self, device: &Device, encoder: &mut CommandEncoder, target: &TextureView, commands: &[SdfCommand], clear_color: Option<Color>, )

Render a sorted slice of SDF commands.

Commands should be pre-sorted by layer. Within each pipeline key, instances are batched into a single instanced draw call.

Call prepare() once per frame before calling render(). clear_color: Some(color) -> LoadOp::Clear, None -> LoadOp::Load.

pub fn pipeline_count(&self) -> usize

Number of cached pipelines (useful for diagnostics).

pub fn clear(&mut self)

Remove all cached pipelines (e.g. after a hot-reload).
