Detailed Description

Immutable type model for the donner::gpu::shader IR.

The type surface covers exactly what Donner's pipeline families require: scalars, vectors, mat4x4f, sized and runtime arrays, structs, and the texture_2d<f32> / sampler / write-only storage texture resource types. Types are immutable values with deep equality, so identical types compare equal deterministically regardless of construction order.

Class Documentation

◆ donner::gpu::shader::IrType::Member

struct donner::gpu::shader::IrType::Member

One named member of a struct type.

Class Members
RcString	name	Member name; unique within the struct.
IrType	type	Member type.

Enumeration Type Documentation

◆ ScalarKind

enum class donner::gpu::shader::ScalarKind : uint8_t

strong

Scalar component types.

Enumerator
Bool	bool. Not host-shareable; no layout.
I32	32-bit signed integer.
U32	32-bit unsigned integer.
F32	32-bit float.

◆ StorageTextureFormat

enum class donner::gpu::shader::StorageTextureFormat : uint8_t

strong

Texel format of a write-only storage texture. Only the format the filter pipelines write is modeled; every backend supports it as a storage-image format without an extended-format capability.

Enumerator
Rgba8Unorm	8-bit RGBA, unsigned normalized.
