Enum wgpu::ShaderSource

source ·
#[non_exhaustive]
pub enum ShaderSource<'a> { SpirV(Cow<'a, [u32]>), Glsl { shader: Cow<'a, str>, stage: ShaderStage, defines: FastHashMap<String, String>, }, Wgsl(Cow<'a, str>), Naga(Cow<'static, Module>), }
Expand description

Source of a shader module.

The source will be parsed and validated.

Any necessary shader translation (e.g. from WGSL to SPIR-V or vice versa) will be done internally by wgpu.

This type is unique to the Rust API of wgpu. In the WebGPU specification, only WGSL source code strings are accepted.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

SpirV(Cow<'a, [u32]>)

Available on crate feature spirv only.

SPIR-V module represented as a slice of words.

See also: util::make_spirv, include_spirv

§

Glsl

Fields

§shader: Cow<'a, str>

The source code of the shader.

§stage: ShaderStage

The shader stage that the shader targets. For example, naga::ShaderStage::Vertex

§defines: FastHashMap<String, String>

Defines to unlock configured shader features.

Available on crate feature glsl only.

GLSL module as a string slice.

Note: GLSL is not yet fully supported and must be a specific ShaderStage.

§

Wgsl(Cow<'a, str>)

Available on crate feature wgsl only.

WGSL module as a string slice.

§

Naga(Cow<'static, Module>)

Available on crate feature naga-ir only.

Naga module.
