Enum Dx12SwapchainKind

pub enum Dx12SwapchainKind {
    DxgiFromHwnd,
    DxgiFromVisual,
}

Selects which kind of swapchain to use on DX12.

Variants

DxgiFromHwnd

Use a DXGI swapchain made directly from the window’s HWND.

This does not support transparency but has better support from developer tooling from RenderDoc.

DxgiFromVisual

Use a DXGI swapchain made from a DirectComposition visual made automatically from the window’s HWND.

This creates a single IDCompositionVisual over the entire window that is used by the Surface. If a user wants to manage the composition tree themselves, they should create their own device and composition, and pass the relevant visual down via SurfaceTargetUnsafe::CompositionVisual.

This supports transparent windows, but does not have support from RenderDoc.

Implementations

impl Dx12SwapchainKind

pub fn from_env() -> Option<Dx12SwapchainKind>

Choose which presentation system to use from the environment variable WGPU_DX12_PRESENTATION_SYSTEM.

Valid values, case insensitive:

• DxgiFromVisual or Visual
• DxgiFromHwnd or Hwnd for Self::DxgiFromHwnd

pub fn with_env(self) -> Dx12SwapchainKind

Takes the given presentation system, modifies it based on the WGPU_DX12_PRESENTATION_SYSTEM environment variable, and returns the result.

See from_env for more information.

Trait Implementations

impl Clone for Dx12SwapchainKind

fn clone(&self) -> Dx12SwapchainKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Dx12SwapchainKind

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

Formats the value using the given formatter.

impl Default for Dx12SwapchainKind

fn default() -> Dx12SwapchainKind

Returns the “default value” for a type.

impl PartialEq for Dx12SwapchainKind

fn eq(&self, other: &Dx12SwapchainKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
