Struct ServerCompositionDrawingSurface 

pub struct ServerCompositionDrawingSurface { /* private fields */ }

The server-side counterpart of a CompositionDrawingSurface: a surface whose content is a snapshot of an imported GPU image.

Implementations

impl ServerCompositionDrawingSurface

pub fn new( compositor: &Rc<ServerCompositor>, ) -> Rc<ServerCompositionDrawingSurface>

pub fn bitmap_ref(&self) -> Option<RefCounted<SharedBitmapImpl>>

The counted reference to the content of the surface.

pub fn update_with_automatic_sync( &self, image: &ServerImportedGpuImage, ) -> Result<(), ServerJobError>

pub fn update_with_keyed_mutex( &self, image: &ServerImportedGpuImage, acquire_index: u32, release_index: u32, ) -> Result<(), ServerJobError>

pub fn update_with_semaphores( &self, image: &ServerImportedGpuImage, wait: &ServerImportedGpuSemaphore, signal: &ServerImportedGpuSemaphore, ) -> Result<(), ServerJobError>

pub fn update_with_timeline_semaphores( &self, image: &ServerImportedGpuImage, wait: &ServerImportedGpuSemaphore, wait_for_value: u64, signal: &ServerImportedGpuSemaphore, signal_value: u64, ) -> Result<(), ServerJobError>

Trait Implementations

impl IServerCompositionSurface for ServerCompositionDrawingSurface

fn bitmap(&self) -> Option<Arc<SharedBitmapImpl>>

The current content of the surface.

fn changed(&self) -> &ServerCompositionSurfaceChanged

Raised when the content changed.

impl IServerObject for ServerCompositionDrawingSurface

fn dispose(&self)

Releases the object: it has been disposed on the UI thread.

fn as_surface(self: Rc<Self>) -> Option<Rc<dyn IServerCompositionSurface>>

The object as a composition surface, if it is one.

fn as_any(&self) -> &dyn Any

fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any>

fn deserialize_changes_core( &self, _reader: &mut BatchStreamReader<'_>, _committed_at: Duration, )

Reads the changes of the object from a batch.

fn values_invalidated(&self)

Called after a group of values of the object changed.

fn deserialize_changes( &self, reader: &mut BatchStreamReader<'_>, committed_at: Duration, )

Applies the changes of the object from a batch.

fn as_render_resource(self: Rc<Self>) -> Option<Rc<dyn IServerRenderResource>>

The object as a render resource, if it is one.

fn as_brush(self: Rc<Self>) -> Option<Rc<dyn IBrush>>

The object as a brush, if it is a server-side brush.

fn as_pen(self: Rc<Self>) -> Option<Rc<dyn IPen>>

The object as a pen, if it is a server-side pen.

fn as_render_data_geometry( self: Rc<Self>, ) -> Option<Rc<dyn IRenderDataGeometry>>

The object as a geometry usable by render data, if it is a server-side geometry.

fn as_transform(self: Rc<Self>) -> Option<Rc<dyn ITransform>>

The object as a transform, if it is a server-side transform.

fn as_gradient_stop(self: Rc<Self>) -> Option<Rc<dyn IGradientStop>>

The object as a gradient stop, if it is a server-side gradient stop.

fn as_animated(self: Rc<Self>) -> Option<Rc<dyn IAnimatedServerObject>>

The object as an animatable object, if it is one.

fn get_props(&self, _type_id: TypeId) -> Option<&dyn Any>

The generated property block of the given type embedded in the object, if it has one. A class that embeds generated properties forwards to their find_props; composition properties locate their fields through it.
