Type Alias RefNode

pub type RefNode = RcRefCell<NodeImpl>;

Opaque DOM tree node reference. This is the type used by this implementation as the concrete type for the NodeRef associated type in the Node trait.

This is the common response type for DOM actions and can be cast to specific traits either by-hand or using the xml_dom::convert module. Also, note that this type supportsPartialEq and so two nodes can be tested to ensure they are the same.
