Required Methods§

source

fn create_surface( &mut self, parent_surface_id: Option<u32>, surface_id: u32, scanout_id: Option<u32>, display_params: &DisplayParameters, surf_type: SurfaceType ) -> GpuDisplayResult<Box<dyn GpuDisplaySurface>>

Creates a surface with the given parameters. The display backend is given a non-zero surface_id as a handle for subsequent operations.

Provided Methods§

source

fn pending_events(&self) -> bool

Returns true if there are events that are on the queue.

source

fn flush(&self)

Sends any pending commands to the compositor.

source

fn next_event(&mut self) -> GpuDisplayResult<u64>

Returns the surface descirptor associated with the current event

source

fn handle_next_event( &mut self, _surface: &mut Box<dyn GpuDisplaySurface> ) -> Option<GpuDisplayEvents>

Handles the event from the compositor, and returns an list of events

source

fn import_resource( &mut self, _import_id: u32, _surface_id: u32, _external_display_resource: DisplayExternalResourceImport<'_> ) -> Result<()>

Imports a resource into the display backend. The display backend is given a non-zero import_id as a handle for subsequent operations.

source

fn release_import(&mut self, _import_id: u32, _surface_id: u32)

Frees a previously imported resource.
