Trait Implementations

impl DeviceAPI for HeadlessDevice

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

The transform from native coordinates to the floor.

fn viewports(&self) -> Viewports

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 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.
