A trait for using an XR device

Required Methods

fn create_layer( &mut self, context_id: ContextId, init: LayerInit, ) -> Result<LayerId, Error>

Create a new layer

fn destroy_layer(&mut self, context_id: ContextId, layer_id: LayerId)

Destroy a layer

fn floor_transform(&self) -> Option<RigidTransform3D<f32, Native, Floor>>

The transform from native coordinates to the floor.

fn viewports(&self) -> Viewports

fn begin_animation_frame( &mut self, layers: &[(ContextId, LayerId)], ) -> Option<Frame>

Begin an animation frame.

fn end_animation_frame(&mut self, layers: &[(ContextId, LayerId)])

End an animation frame, render the layer to the device, and block waiting for the next frame.

fn initial_inputs(&self) -> Vec<InputSource>

Inputs registered with the device on initialization. More may be added, which should be communicated through a yet-undecided event mechanism

fn set_event_dest(&mut self, dest: Sender<Event>)

Sets the event handling channel

fn quit(&mut self)

Quit the session

fn set_quitter(&mut self, quitter: Quitter)

fn update_clip_planes(&mut self, near: f32, far: f32)

fn granted_features(&self) -> &[String]

Provided Methods

fn environment_blend_mode(&self) -> EnvironmentBlendMode

fn request_hit_test(&mut self, _source: HitTestSource)

fn cancel_hit_test(&mut self, _id: HitTestId)

fn update_frame_rate(&mut self, rate: f32) -> f32

fn supported_frame_rates(&self) -> Vec<f32>

fn reference_space_bounds(&self) -> Option<Vec<Point2D<f32, Floor>>>
