Represents a type declared in a SPIRV module.

Types are declared in a hierarchy, with e.g. pointers relying on previously declared types as pointed-to types.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

An unsupported type

Void

The Void type

Bool

A boolean

Int32

A signed 32-Bit integer

UInt32

An unsigned 32-Bit integer

Float32

A 32-Bit float

Vec2

A 2 component, 32-Bit vector (GLSL: vec2)

Vec3

A 3 component, 32-Bit vector (GLSL: vec3)

Vec4

A 4 component, 32-Bit vector (GLSL: vec4)

Mat3

A 3x3, 32-Bit Matrix (GLSL: mat3)

Mat4

A 4x4, 32-Bit Matrix (GLSL: mat4)

Image2D

A 2D image

Fields

depth: bool

true if this image is a depth image

sampled: bool

true if this image can be sampled from

format: u32

SPIRV code of the images format (should always be 0 in Vulkan)

Sampler

An opaque sampler object

SampledImage

A combined image and sampler (Vulkan: CombinedImageSampler descriptor)

Fields

image_type_id: u32

type id of the image contained in the SampledImage

Array

Either a static array with known length (length is Some) or dynamic array with unknown length (length is None)

Fields

element_type_id: u32

type id of the contained type

length: Option<u32>

length of the array (if known)

Struct

A struct containing other types

Fields

name: Option<String>

elements: Vec<StructMember>

members of the struct, in the order they appear in the SPIRV module (not necessarily ascending offsets)

Pointer

A pointer pointing to another type

Fields

storage_class: StorageClass

The type of storage this pointer points to

pointed_type_id: u32

The type id of the pointed-to type
