Struct CompositionDrawingSurface 

pub struct CompositionDrawingSurface(/* private fields */);

A composition surface whose content is set from imported GPU images.

Implementations

impl CompositionDrawingSurface

pub fn update_with_keyed_mutex_async( &self, image: &dyn ICompositionImportedGpuImage, acquire_index: u32, release_index: u32, ) -> ServerJobTask<()>

Updates the surface contents using an imported memory image using a keyed mutex as the means of synchronization

acquire_index is the mutex key to wait for before accessing the image, release_index the mutex key to release for after accessing the image. Returns a task that completes when update operation is completed and user code is free to destroy or dispose the image.

pub fn update_with_semaphores_async( &self, image: &dyn ICompositionImportedGpuImage, wait_for_semaphore: &dyn ICompositionImportedGpuSemaphore, signal_semaphore: &dyn ICompositionImportedGpuSemaphore, ) -> ServerJobTask<()>

Updates the surface contents using an imported memory image using a semaphore pair as the means of synchronization

wait_for_semaphore is the semaphore to wait for before accessing the image, signal_semaphore the semaphore to signal after accessing the image.

pub fn update_with_timeline_semaphores_async( &self, image: &dyn ICompositionImportedGpuImage, wait_for_semaphore: &dyn ICompositionImportedGpuSemaphore, wait_for_value: u64, signal_semaphore: &dyn ICompositionImportedGpuSemaphore, signal_value: u64, ) -> ServerJobTask<()>

Updates the surface contents using an imported memory image using a semaphore pair as the means of synchronization

The semaphores are timeline semaphores: wait_for_value is the value to wait for before accessing the image, signal_value the value to signal after accessing it.

pub fn update_async( &self, image: &dyn ICompositionImportedGpuImage, ) -> ServerJobTask<()>

Updates the surface contents using an unspecified automatic means of synchronization provided by the underlying platform

pub fn dispose(&self)
