Trait cursive::view::AnyView[−][src]

pub trait AnyView {
    fn as_any(&self) -> &Any;
    fn as_any_mut(&mut self) -> &mut Any;
    fn as_boxed_any(self: Box<Self>) -> Box<Any>;
}

A view that can be downcasted to its concrete type.

This trait is automatically implemented for any T: View.

Required Methods

`fn as_any(&self) -> &Any`

Downcast self to a Any.

`fn as_any_mut(&mut self) -> &mut Any`

Downcast self to a mutable Any.

Important traits for Box<R>

impl<R> Read for Box<R> where
    R: Read + ?Sized, impl<W> Write for Box<W> where
    W: Write + ?Sized, impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,     type Item = <I as Iterator>::Item;

`fn as_boxed_any(self: Box<Self>) -> Box<Any>`

Returns a boxed any from a boxed self.

Can be used before Box::downcast().

Examples

let boxed: Box<View> = Box::new(TextView::new("text"));
let text: Box<TextView> = boxed.as_boxed_any().downcast().unwrap();
