Trait NotificationManager 

pub trait NotificationManager {
    // Required methods
    fn new_notification(
        &self,
        notification: Notification,
    ) -> Result<(), NotiError>;
    fn close_notification(&self, id: u32) -> Result<(), NotiError>;
}

This trait’s implementation is necessary for passing spell’s generated widget into the notification field of cast_spell macro. It is important to note that implementation of this trait is not on the spell generated widget/window but on the slint generated window. For example, a window with name TopBar will have a spell implemetation TopBarSpell. This trait will be implemented over TopBar.
