You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: view.rs
    path of file: ./repos/vizia/crates/vizia_core/src
    
    the code of the file until where you have to start completion: //! Views are used to visually present model data and to act as controls which, when interacted with, send events to mutate model data.
//!
//!
    
    ///     fn event(&mut self, cx: &mut EventContext, event: &mut Event) {
    ///         event.map(|window_event, meta| match window_event{
    ///             WindowEvent::MouseDown(_) => {
    ///                 if meta.target == cx.current() {
    ///                     // Emit a `WindowClose` event when this view is clicked on.
    ///                     cx.emit(WindowEvent::WindowClose);
    ///                 }
    ///             }
    ///
    ///             _=> {}
    ///         });
    ///     }
