Struct cursive_core::views::BoxedView

pub struct BoxedView { /* fields omitted */ }

A boxed View.

It derefs to the wrapped view.

Implementations

impl BoxedView

pub fn new(view: Box<dyn View>) -> Self

Creates a new BoxedView around the given boxed view.

pub fn boxed<T>(view: T) -> Self where
    T: IntoBoxedView, 

Box the given view

pub fn unwrap(self) -> Box<dyn View>

Returns the inner boxed view.

Methods from Deref<Target = dyn View>

pub fn downcast_ref<T: Any>(&self) -> Option<&T>

Attempts to downcast self to a concrete type.

pub fn downcast_mut<T: Any>(&mut self) -> Option<&mut T>

Attempts to downcast self to a concrete type.

pub fn is<T: Any>(&self) -> bool

Checks if this view is of type T.
