Struct PipelineCache 

pub struct PipelineCache { /* private fields */ }

PipelineCache holds compiled render-pipeline variants.

The cache grows only. Misses compile synchronously on first use.

Implementations

impl PipelineCache

pub fn new(device: &Device, uniforms_layout: &BindGroupLayout) -> Self

new compiles the shader module and pipeline layouts for device.

pub fn blend_bind_layout(&self) -> &BindGroupLayout

blend_bind_layout returns the group-1 layout for advanced-blend bind groups.

Bindings are destination, sampler, and source.

pub fn texture_bind_layout(&self) -> &BindGroupLayout

texture_bind_layout returns the group-1 layout for image bind groups.

Bindings are texture and sampler.

pub fn ensure(&mut self, device: &Device, key: PipelineKey)

ensure compiles the pipeline for key if it is not already cached.

pub fn get(&self, key: &PipelineKey) -> &RenderPipeline

get returns a pipeline previously compiled by Self::ensure.

Panics if key was never ensured.
