Struct relm::Component

#[must_use]
pub struct Component<WIDGET: Widget> { /* fields omitted */ }

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).

Methods

impl<WIDGET: Widget> Component<WIDGET>

fn stream(&self) -> &EventStream<WIDGET::Msg>

Get the event stream of the widget. This is used internally by the library.

fn widget(&self) -> &WIDGET

Get the widget of this component.
