Expand description

The window/canvas/surface/swap-chain/etc. a surface is attached to, for use with unsafe surface creation.

This is either a window or an actual web canvas depending on the platform and enabled features. Refer to the individual variants for more information.

See also SurfaceTarget for safe variants.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

RawHandle

Raw window & display handle.

If the specified display and window handle are not supported by any of the backends, then the surface will not be supported by any adapters.

§Safety

  • raw_window_handle & raw_display_handle must be valid objects to create a surface upon.
  • raw_window_handle & raw_display_handle must remain valid until after the returned Surface is dropped.

Fields

§raw_display_handle: RawDisplayHandle

Raw display handle, underlying display must outlive the surface created from this.

§raw_window_handle: RawWindowHandle

Raw display handle, underlying window must outlive the surface created from this.

§

Drm

Surface from a DRM device.

If the specified DRM configuration is not supported by any of the backends, then the surface will not be supported by any adapters.

§Safety

  • All parameters must point to valid DRM values and remain valid for as long as the resulting Surface exists.
  • The file descriptor (fd), plane, connector, and mode configuration must be valid and compatible.

Fields

§fd: i32

The file descriptor of the DRM device.

§plane: u32

The plane index on which to create the surface.

§connector_id: u32

The ID of the connector associated with the selected mode.

§width: u32

The display width of the selected mode.

§height: u32

The display height of the selected mode.

§refresh_rate: u32

The display refresh rate of the selected mode multiplied by 1000 (e.g., 60Hz → 60000).

Implementations§

Source§

impl SurfaceTargetUnsafe

Source

pub unsafe fn from_window<T>( window: &T, ) -> Result<SurfaceTargetUnsafe, HandleError>
where T: HasDisplayHandle + HasWindowHandle,

Creates a SurfaceTargetUnsafe::RawHandle from a window.

§Safety
  • window must outlive the resulting surface target (and subsequently the surface created for this target).
