Detailed Description

Bind group indices of the SVG color-matrix filter program.

Split out from the program header so a host can build the program's bind group layout without linking the shader IR. The pipeline that does so consumes build-time emitted WGSL, and pulling in the IR for an enum would put the emitters back in binaries that exist to avoid them.

Enumeration Type Documentation

FilterColorMatrixBinding

enum class donner::gpu::shader::programs::FilterColorMatrixBinding : uint32_t

strong

Bind group indices of the color-matrix filter program, shared by the IR builder and every host that creates its bind group layout.

Enumerator
InputTexture	Sampled texture_2d<f32> source.
OutputTexture	texture_storage_2d<rgba32float, write> destination.
Params	Uniform buffer holding the five matrix columns.

Variable Documentation

kFilterColorMatrixWorkgroupSize

uint32_t donner::gpu::shader::programs::kFilterColorMatrixWorkgroupSize = 8

inlineconstexpr

Workgroup size the entry point declares.

One definition, read by the IR builder that writes the shader and by every host that creates the pipeline or sizes a dispatch from it. A host restating it could drift, and a larger stale copy would silently under-dispatch, leaving the tail of the destination unwritten.
