Enum wgpu::Dx12Compiler

pub enum Dx12Compiler {
    Fxc,
    DynamicDxc {
        dxc_path: PathBuf,
        dxil_path: PathBuf,
    },
    StaticDxc,
}

Selects which DX12 shader compiler to use.

If the Dxc option is selected, but dxcompiler.dll and dxil.dll files aren’t found, then this will fall back to the Fxc compiler at runtime and log an error.

wgpu::utils::init::dx12_shader_compiler_from_env can be used to set the compiler from the WGPU_DX12_SHADER_COMPILER environment variable, but this should only be used for testing.

Variants

Fxc

The Fxc compiler (default) is old, slow and unmaintained.

However, it doesn’t require any additional .dlls to be shipped with the application.

DynamicDxc

Fields

dxc_path: PathBuf

Path to dxcompiler.dll.

dxil_path: PathBuf

Path to dxil.dll.

The Dxc compiler is new, fast and maintained.

However, it requires both dxcompiler.dll and dxil.dll to be shipped with the application. These files can be downloaded from https://github.com/microsoft/DirectXShaderCompiler/releases.

Minimum supported version: v1.5.2010

It also requires WDDM 2.1 (Windows 10 version 1607).

StaticDxc

The statically-linked variant of Dxc. The static-dxc feature is required to use this.
