Struct gpu_display::gpu_display_stub::DisplayStub

pub struct DisplayStub {
    event: Event,
}

Fields

event: Event

This event is never triggered and is used solely to fulfill AsRawDescriptor.

Implementations

impl DisplayStub

pub fn new() -> GpuDisplayResult<DisplayStub>

Trait Implementations

impl AsRawDescriptor for DisplayStub

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor.

impl DisplayT for DisplayStub

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.

fn pending_events(&self) -> bool

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

fn flush(&self)

Sends any pending commands to the compositor.

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

Returns the surface descirptor associated with the current event

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

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.

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

Frees a previously imported resource.
