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. Read moresource§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

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. Read moresource§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert
