Supports conversion to Any. Traits to be extended by impl_downcast! must extend Downcast.

Notable traits for Box<R, Global>

impl<R> Read for Box<R, Global> where
    R: Read + ?Sized, impl<W> Write for Box<W, Global> where
    W: Write + ?Sized, impl<F, A> Future for Box<F, A> where
    F: Future + Unpin + ?Sized,
    A: Allocator + 'static,  type Output = <F as Future>::Output;impl<I, A> Iterator for Box<I, A> where
    A: Allocator,
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

pub fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

pub fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

pub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
