Struct gpu_display::gpu_display_wl::DisplayWl

pub struct DisplayWl {
    dmabufs: HashMap<u32, DwlDmabuf>,
    ctx: DwlContext,
    current_event: Option<dwl_event>,
    mt_tracking_id: u16,
}

A connection to the compositor and associated collection of state.

The user of GpuDisplay can use AsRawDescriptor to poll on the compositor connection’s file descriptor. When the connection is readable, dispatch_events can be called to process it.

Fields

dmabufs: HashMap<u32, DwlDmabuf>

ctx: DwlContext

current_event: Option<dwl_event>

mt_tracking_id: u16

Implementations

impl DisplayWl

pub fn new(wayland_path: Option<&Path>) -> GpuDisplayResult<DisplayWl>

Opens a fresh connection to the compositor.

fn ctx(&self) -> *mut dwl_context

fn pop_event(&self) -> dwl_event

fn next_tracking_id(&mut self) -> i32

fn current_tracking_id(&self) -> i32

Trait Implementations

impl AsRawDescriptor for DisplayWl

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor.

impl DisplayT for DisplayWl

fn pending_events(&self) -> bool

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

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 flush(&self)

Sends any pending commands to the compositor.

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 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, _surface_id: u32, import_id: u32)

Frees a previously imported resource.
