Trait AppComponent 

pub trait AppComponent<Msg, UserEvent>: Component + Any
where
    Msg: PartialEq,
    UserEvent: Eq + PartialEq + Clone,
{
    // Required method
    fn on(&mut self, ev: &Event<UserEvent>) -> Option<Msg>;
}

The app component describes the application level component, which is a wrapper around the Component, which, in addition to all the methods exposed by the base component, it will handle the Events coming from the View.

The Event are passed to the on method, which will eventually return a Msg, which is defined in your application as an enum. In your application you should have a Component for each element on your UI, but the logic to implement is very tiny, since the most of the work should already be done into the Component and many of them are available in the standard library at tui-realm-stdlib.

Don’t forget you can find an example in the examples/ directory and you can discover many more information about components in the repository documentation.

Required Methods

fn on(&mut self, ev: &Event<UserEvent>) -> Option<Msg>

Handle input event and update internal states. Returns a Msg to the view. If None is returned it means there’s no message to return for the provided event.

Implementations

impl<Msg, UserEvent> dyn AppComponent<Msg, UserEvent>

where Msg: PartialEq, UserEvent: Eq + PartialEq + Clone,

pub fn as_any(&self) -> &dyn Any

Convenience function to cast to Any.

pub fn as_any_mut(&mut self) -> &mut dyn Any

Convenience function to cast to Any mutably.
