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