Enum wgpu::ShaderSource

#[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>),
}

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.

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.

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

Available on crate feature spirv only.

SPIR-V module represented as a slice of words.

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>)

WGSL module as a string slice.

Naga(Cow<'static, Module>)

Available on crate feature naga only.

Naga module.
