/// Wraps this view into an `NamedView` with the given id.
///
/// This is just a shortcut for `NamedView::new(id, self)`
///
/// You can use the given id to find the view in the layout tree.
///
/// # Examples
///
/// ```rust
/// # use cursive_core::Cursive;
/// # use cursive_core::views::TextView;
/// # use cursive_core::view::Resizable;
/// use cursive_core::view::Nameable;
///
/// let mut siv = Cursive::new();
/// siv.add_layer(TextView::new("foo").with_name("text").fixed_width(10));
///
/// // You could call this from an event callback
/// siv.call_on_name("text", |view: &mut TextView| {
/// view.set_content("New content!");
/// });
/// ```
///
/// # Notes
///
/// You should call this directly on the view you want to retrieve later,
/// before other wrappers like [`fixed_width`]. Otherwise, you would be
/// retrieving a [`ResizedView`]!
///
/// [`fixed_width`]: crate::view::Resizable::fixed_width
