Expand description

State stored per viewport.

Mostly for internal use. Things here may move and change without warning.

Fields§

§class: ViewportClass

The type of viewport.

This will never be ViewportClass::Embedded, since those don’t result in real viewports.

§builder: ViewportBuilder

The latest delta

§viewport_ui_cb: Option<Arc<DeferredViewportUiCallback>>

The user-code that shows the GUI, used for deferred viewports.

None for immediate viewports.

§input: InputState§this_frame: FrameState

State that is collected during a frame and then cleared.

§prev_frame: FrameState

The final FrameState from last frame.

Only read from.

§used: bool

Has this viewport been updated this frame?

§repaint: ViewportRepaintInfo

State related to repaint scheduling.

§hits: WidgetHits

Which widgets are under the pointer?

§interact_widgets: InteractionSnapshot

What widgets are being interacted with this frame?

Based on the widgets from last frame, and input in this frame.

§graphics: GraphicLayers§output: PlatformOutput§commands: Vec<ViewportCommand>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
