Struct Render

pub struct Render<Ev> { /* private fields */ }

Use an instance of Render to notify the Shell that it should update the user interface. This assumes a declarative UI framework is used in the Shell, which will take the ViewModel provided by Core::view and reconcile the new UI state based on the view model with the previous one.

For imperative UIs, the Shell will need to understand the difference between the two view models and update the user interface accordingly.

impl<Ev> Render<Ev>

where Ev: 'static,

Public API of the capability, called by App::update.

pub fn new(context: CapabilityContext<RenderOperation, Ev>) -> Self
