Trait gui::Widget

pub trait Widget: Handleable + Renderable + Object + Debug + 'static {
    fn type_id(&self) -> TypeId;
}

A widget as used by a Ui.

In addition to taking care of Id management and parent-child relationships, the Ui is responsible for dispatching events to widgets and rendering them. Hence, a widget usable for the Ui needs to implement Handleable, Renderable, and Object.
