Struct relm::Component

#[must_use]
pub struct Component<WIDGET: Widget>(_)
 where
    WIDGET::Model: Clone;

Widget that was added by the ContainerWidget::add_widget() method.

Warning

You must keep your components as long as you want them to send/receive events. Common practice is to store Components in the Widget struct (see the communication example). The #[widget] attribute takes care of storing them in the struct automatically (see the communication-attribute example).
