Struct BlitPipeline 

pub(crate) struct BlitPipeline {
    pipeline: RenderPipeline,
    pipeline_over: RenderPipeline,
    bind_group_layout: BindGroupLayout,
    sampler: Sampler,
}

Fields

pipeline: RenderPipeline

BlendState::REPLACE — copies source pixels exactly. Used for the final dest_rt → view flush at end of slow-path render.

pipeline_over: RenderPipeline

BlendState::ALPHA_BLENDING — source-over composite. Used by the clip dispatch path to layer a masked RT on top of the in-progress destination.

bind_group_layout: BindGroupLayout

sampler: Sampler

Implementations

impl BlitPipeline

pub(crate) fn new(app: &Application, output_format: TextureFormat) -> Self

pub(crate) fn blit( &self, app: &Application, src: &RenderTexture, target_view: &TextureView, )

Sample src and write it onto target_view, replacing the destination pixels. Used for the final dest_rt → view flush.

pub(crate) fn compose_over( &self, app: &Application, src: &RenderTexture, target_rt: &RenderTexture, )

Sample src and source-over composite onto target_rt, preserving the destination’s existing content under transparent regions of src. Used by the clip dispatcher to layer a masked RT on top of the in-progress destination.

fn run( &self, app: &Application, src: &RenderTexture, target_view: &TextureView, pipeline: &RenderPipeline, clear: bool, )
