Struct BlendPipelineSet

Source

pub struct BlendPipelineSet {
    pub globals_layout: BindGroupLayout,
    pub normal: RenderPipeline,
    pub multiply: RenderPipeline,
    pub screen: RenderPipeline,
    pub copy: RenderPipeline,
    pub destination: RenderPipeline,
}

Expand description

A set of pre-compiled solid-pass pipeline variants, one per blend mode.

Building this set at startup avoids pipeline creation at runtime when the active blend mode changes. The set shares the globals_layout bind group layout so a single globals bind group can be used across all modes.

Fields§

§globals_layout: BindGroupLayout

Globals bind group layout (viewport uniform, group 0).

§normal: RenderPipeline

Normal blend mode pipeline (source-over).

§multiply: RenderPipeline

Multiply blend mode pipeline.

§screen: RenderPipeline

Screen blend mode pipeline.

§copy: RenderPipeline

Copy blend mode pipeline (replace destination).

§destination: RenderPipeline

Destination blend mode pipeline (keep destination, ignore source).

Implementations§

Source §

impl BlendPipelineSet

Source

pub fn new(device: &Device, sample_count: u32) -> Self

Build all blend-mode pipeline variants.

sample_count controls MSAA (1 = no MSAA).

Source

pub fn pipeline_for(&self, mode: BlendMode) -> &RenderPipeline

Return a reference to the pipeline for the given BlendMode.

Modes without a dedicated pipeline (Overlay, Darken, Lighten) fall back to the Normal pipeline.
