Struct Dx12BackendOptions 

pub struct Dx12BackendOptions {
    pub shader_compiler: Dx12Compiler,
    pub presentation_system: Dx12SwapchainKind,
    pub latency_waitable_object: Dx12UseFrameLatencyWaitableObject,
    pub force_shader_model: ForceShaderModelToken,
    pub agility_sdk: Option<Dx12AgilitySDK>,
}

Configuration for the DX12 backend.

Part of BackendOptions.

Fields

shader_compiler: Dx12Compiler

Which DX12 shader compiler to use.

presentation_system: Dx12SwapchainKind

Presentation system to use.

latency_waitable_object: Dx12UseFrameLatencyWaitableObject

Whether to wait for the latency waitable object before acquiring the next swapchain image.

force_shader_model: ForceShaderModelToken

For use with passthrough shaders. Expose features as if this shader model is present, even if you do not intend to ship DXC with your app.

This does not override the device’s shader model version, only the external shader compiler’s version.

agility_sdk: Option<Dx12AgilitySDK>

Optional Agility SDK configuration for using the Independent Devices API.

When set, wgpu will attempt to load the specified D3D12 runtime via the Independent Devices API. If the API is unavailable or the configuration is invalid, it falls back to the system-installed D3D12 runtime.

Can also be set via WGPU_DX12_AGILITY_SDK_PATH and WGPU_DX12_AGILITY_SDK_VERSION environment variables.

Implementations

impl Dx12BackendOptions

pub fn from_env_or_default() -> Dx12BackendOptions

Choose DX12 backend options by calling from_env on every field.

See those methods for more information.

pub fn with_env(self) -> Dx12BackendOptions

Takes the given options, modifies them based on the environment variables, and returns the result.

This is equivalent to calling with_env on every field.

Trait Implementations

impl Clone for Dx12BackendOptions

fn clone(&self) -> Dx12BackendOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Dx12BackendOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Dx12BackendOptions

fn default() -> Dx12BackendOptions

Returns the “default value” for a type.
