Trait Implementations

impl<C: Component> ComponentController<C> for Controller<C>

fn sender(&self) -> &Sender<C::Input>

Provides access to the component’s sender.

fn state(&self) -> &StateWatcher<C>

Provides access to the state of a component.

fn widget(&self) -> &C::Root

Returns the root widget of the component.

fn detach_runtime(&mut self)

Dropping this type will usually stop the runtime of the component. With this method you can give the runtime a static lifetime. In other words, dropping the controller or connector will not stop the runtime anymore, instead it will run until the app is closed.

fn emit(&self, event: C::Input)

Emits an input to the component.

fn model(&self) -> Ref<'_, C>

Returns a reference to the Component.

fn widgets(&self) -> Ref<'_, C::Widgets>

Returns a reference to the Component::Widgets.

impl<C> Debug for Controller<C>where
    C: Component + Debug,
    C::Widgets: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
