//! Inheritance and casting
//! =======================
//!
//! For all DOM interfaces `Foo` in an inheritance chain, a
//! `dom::bindings::inheritance::FooCast` provides methods to cast
//! to other types in the inheritance chain. For example:
//! All DOM interfaces part of an inheritance chain (i.e. interfaces
//! that derive others or are derived from) implement the trait `Castable`
//! which provides both downcast and upcasts.
//!
//! ```ignore
//! # use script::dom::bindings::inheritance::{NodeCast, HTMLElementCast};
//! # use script::dom::bindings::inheritance::Castable;
//! # use script::dom::element::Element;
//! # use script::dom::node::Node;
//! # use script::dom::htmlelement::HTMLElement;
//! fn f(element: &Element) {
//! let base = element.upcast::<Node>();
//! let derived = element.downcast::<HTMLElement>();
//! let derived = element.downcast::<HTMLElement>().unwrap();
//! }
//! ```
//!
