Source of a shader module.

Variants

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

Tuple Fields

0: Cow<'a, [u32]>

SPIR-V module represented as a slice of words.

wgpu will attempt to parse and validate it, but the original binary is passed to gfx-rs and spirv_cross for translation.

Glsl

Fields

shader: Cow<'a, str>

The shaders code

stage: ShaderStage

Stage in which the GLSL shader is for example: naga::ShaderStage::Vertex

defines: FastHashMap<String, String>

Defines to unlock configured shader features

GLSL module as a string slice.

wgpu will attempt to parse and validate it. The module will get passed to wgpu-core where it will translate it to the required languages.

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

Wgsl(Cow<'a, str>)

Tuple Fields

0: Cow<'a, str>

WGSL module as a string slice.

wgpu-rs will parse it and use for validation. It will attempt to build a SPIR-V module internally and panic otherwise.

Note: WGSL is not yet supported on the Web.
