[−][src]Trait cursive_core::view::AnyView

pub trait AnyView {
    pub fn as_any(&self) -> &dyn Any;

    pub fn as_any_mut(&mut self) -> &mut dyn Any;

    pub fn as_boxed_any(self: Box<Self>) -> Box<dyn Any>;
}

A view that can be downcasted to its concrete type.

This trait is automatically implemented for any T: View.

Required methods

pub fn as_any(&self) -> &dyn Any[src]

Downcast self to a Any.

pub fn as_any_mut(&mut self) -> &mut dyn Any[src]

Downcast self to a mutable Any.

pub fn as_boxed_any(self: Box<Self>) -> Box<dyn Any>[src]

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();
