Struct CompositionInterop 

pub struct CompositionInterop { /* private fields */ }

The interop of a compositor with the GPU objects of its render interface context.

Implementations

impl CompositionInterop

pub fn new( compositor: &Rc<Compositor>, external_objects: Rc<dyn IExternalObjectsRenderInterfaceContextFeature>, ) -> Rc<CompositionInterop>

Creates the interop over a feature of the render interface.

The feature is an object of the server side and is kept inside the compositor lock from here on: a caller that is not inside the lock hands it over whole, without keeping a clone. (Upstream the constructor runs in a job of the render thread.)

Panics

When the compositor is confined to its render thread and that thread has no context of the render interface: see try_new.

Trait Implementations

impl ICompositionGpuInterop for CompositionInterop

fn import_shared_semaphore( &self, _image: Rc<dyn ICompositionImportableSharedGpuContextSemaphore>, ) -> Rc<dyn ICompositionImportedGpuImage>

Not supported (NotSupportedException upstream).

fn supported_image_handle_types(&self) -> Vec<String>

Returns the list of image handle types supported by the current GPU backend, see KnownPlatformGraphicsExternalImageHandleTypes

fn supported_semaphore_types(&self) -> Vec<String>

Returns the list of semaphore types supported by the current GPU backend, see KnownPlatformGraphicsExternalSemaphoreHandleTypes

fn supported_dma_buf_formats(&self) -> Option<Vec<PlatformGraphicsDrmFormat>>

Returns the DRM format/modifier pairs the current GPU backend can import as KnownPlatformGraphicsExternalImageHandleTypes::DMA_BUF_FILE_DESCRIPTOR images, or None when the backend cannot enumerate them.

fn get_synchronization_capabilities( &self, image_handle_type: &str, ) -> CompositionGpuImportedImageSynchronizationCapabilities

Returns the supported ways to synchronize access to the imported GPU image

fn import_image( &self, handle: Rc<dyn IPlatformHandle>, properties: PlatformGraphicsExternalImageProperties, ) -> Rc<dyn ICompositionImportedGpuImage>

Asynchronously imports a texture. The returned object is immediately usable.

fn import_shared_image( &self, image: Arc<dyn ICompositionImportableSharedGpuContextImage>, ) -> Rc<dyn ICompositionImportedGpuImage>

Asynchronously imports a texture. The returned object is immediately usable. If import operation fails, the caller is responsible for destroying the handle

fn import_semaphore( &self, handle: Rc<dyn IPlatformHandle>, ) -> Rc<dyn ICompositionImportedGpuSemaphore>

Asynchronously imports a semaphore object. The returned object is immediately usable. If import operation fails, the caller is responsible for destroying the handle

fn is_lost(&self) -> bool

Indicates if the device context this instance is associated with is no longer available

fn device_luid(&self) -> Option<Vec<u8>>

The LUID of the graphics adapter used by the compositor

fn set_device_luid(&self, value: Option<Vec<u8>>)

fn device_uuid(&self) -> Option<Vec<u8>>

The UUID of the graphics adapter used by the compositor

fn set_device_uuid(&self, value: Option<Vec<u8>>)
