Implementations

impl GraphicalPresenterSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<GraphicalPresenterEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn present_view( &self, view_spec: ViewSpec, annotation_controller: Option<ClientEnd<AnnotationControllerMarker>>, view_controller_request: Option<ServerEnd<ViewControllerMarker>>, ___deadline: MonotonicInstant, ) -> Result<GraphicalPresenterPresentViewResult, Error>

Presents the view described by view_spec.

If view_controller_request is provided, it will be connected to a ViewController implemented by the GraphicalPresenter server. When the view is dismissed, the ViewController channel is closed with a ZX_OK, at which point it is safe to clean up resources backing the view. To dismiss the view, the client should call ViewController.Dismiss() and wait for the ZX_OK epitaph. Not providing a view_controller_request handle will make it impossible for the client to observe the view’s lifecycle.

• view_spec describes the view to present
• annotation_controller a handle to an AnnotationController, allowing the GraphicalPresenter server to observe and update the view’s annotations.
• view_controller_request an optional request for a controller for the view

• error view_spec must contain view_holder_token and view_ref for Gfx views, OR viewport_creation_token for Flatland views, but never both. If both are set, error PresentViewError.INVALID_ARGS is returned.
• error PresentViewError.INVALID_ARGS if spec.view_holder_token or spec.view_ref are missing or invalid.
