}

The import of GPU objects created outside of the framework into the render context: a feature of the render interface context.

Required Methods

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

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

Imports an image of a context that shares with this one. The image is shared with the thread that made it, which keeps it and disposes it: this is called on the thread that renders.

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

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

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

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

Provided Methods

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
