Struct CompositorResourceHolder 

pub struct CompositorResourceHolder { /* private fields */ }

Holds the server-side counterparts of a media object, one per compositor the object is used with.

Implementations

impl CompositorResourceHolder

pub fn new() -> Self

pub fn is_attached(&self) -> bool

Whether the object is attached to any compositor.

pub fn create_or_add_ref( &self, compositor: &Rc<Compositor>, owner: Option<Rc<dyn ICompositorSerializable>>, factory: impl FnOnce(&Rc<Compositor>) -> ServerObjectId, ) -> (ServerObjectId, bool)

Adds a reference to the counterpart on compositor, creating it with factory if there is none. Returns the counterpart and whether it was created; a newly created counterpart’s owner is registered for serialization.

pub fn try_get_for_compositor( &self, compositor: &Compositor, ) -> Option<ServerObjectId>

pub fn get_for_compositor(&self, compositor: &Compositor) -> ServerObjectId

pub fn release(&self, compositor: &Compositor) -> bool

Drops one reference to the counterpart on compositor. Returns whether it was the last one.

pub fn process_property_change_notification( &self, old_value: Option<&dyn ICompositionRenderResource>, new_value: Option<&dyn ICompositionRenderResource>, )

Moves the references this object holds on a property value from the old value to the new one, on every compositor.

pub fn transitive_release_all( &self, old_resource: &dyn ICompositionRenderResource, )

pub fn transitive_add_ref_all( &self, new_resource: &dyn ICompositionRenderResource, )

pub fn register_for_invalidation_on_all_compositors( &self, serializable: &Rc<dyn ICompositorSerializable>, )

Trait Implementations

impl Default for CompositorResourceHolder

fn default() -> Self

Returns the “default value” for a type.
