Enum EventResult 

pub enum EventResult<Msg> {
    Ignored,
    Consumed,
    Emit(Msg),
}

What a component did with an event, and what should happen next.

Events travel from a component up through its ancestors. This value decides whether that continues: Ignored passes the event to the parent, while both Consumed and Emit stop it there.

The same enum comes back out of Ratcn::handle_event, so the app sees the final outcome after bubbling has finished.

Variants

Ignored

Not handled here. The parent gets a chance at it, and if nothing in the chain handles it the app sees Ignored and can treat it as a global hotkey.

Consumed

Handled, with nothing for the app to do — a keypress that only moved an internal cursor, for example.

Emit(Msg)

Handled, and the app should apply this message. Implies consumed.

Components never write app state themselves; this message is how a change reaches the app’s update function.
