Expand description

Provides call_on<V: View> to views.

This trait is mostly a wrapper around View::call_on_any.

It provides a nicer interface to find a view when you know its type.

Required Methods

Runs a callback on all views identified by sel.

Useful if you have multiple views of the same type with the same name.

Provided Methods

Runs a callback on the view identified by sel.

If the view is found, return the result of callback.

If the view is not found, or if it is not of the asked type, it returns None.

Convenient method to use call_on with a view::Selector::Name.

Convenient method to find a view wrapped in an NamedView.
