Enum ToplevelEvent

pub enum ToplevelEvent {
    Opened {
        id: u32,
        app_id: String,
    },
    Closed {
        id: u32,
    },
}

Wayland ext-foreign-toplevel-list-v1 event delivered to apps via App::on_toplevel_event. Opened fires after the compositor commits the first done for a new handle (so app_id is the value in effect at that point — the protocol allows the compositor to re-commit later, but most don’t). Closed fires when the compositor sends closed and the runtime is about to destroy the handle proxy. Both carry the same id, the Wayland protocol id of the handle, unique within the session and stable for the handle’s lifetime.
