Introduce trait Castable
This trait is used to hold onto the downcast and upcast functions of all castable IDL interfaces. A castable IDL interface is one which either derives from or is derived by other interfaces. The deriving relation is represented by implementations of marker trait DerivedFrom<T: Castable> generated in InheritTypes. /^[ ]*use dom::bindings::codegen::InheritTypes::.*(Base|Cast|Derived)/ { /::[a-zA-Z]+(Base|Cast|Derived);/d s/([{ ])[a-zA-Z]+(Base|Cast|Derived), /\1/g s/([{ ])[a-zA-Z]+(Base|Cast|Derived), /\1/g s/, [a-zA-Z]+(Base|Cast|Derived)([},])/\2/g s/, [a-zA-Z]+(Base|Cast|Derived)([},])/\2/g /\{([a-zA-Z]+(Base|Cast|Derived))?\};$/d s/\{([a-zA-Z_]+)\};$/\1;/ } s/([a-zA-Z]+)Cast::from_ref\(\&?\**([a-zA-Z_]+)(\.r\(\))?\)/\2.upcast::<\1>()/g s/([a-zA-Z]+)Cast::from_ref\(\&?\**([a-zA-Z_]+)(\.[a-zA-Z_]+\(\))?\)/\2\3.upcast::<\1>()/g s/\(([a-zA-Z]+)Cast::from_ref\)/\(Castable::upcast::<\1>\)/g s/([a-zA-Z]+)Cast::from_root/Root::upcast::<\1>/g s/([a-zA-Z]+)Cast::from_layout_js\(\&([a-zA-Z_.]+)\)/\2.upcast::<\1>()/g s/([a-zA-Z]+)Cast::to_ref\(\&?\**([a-zA-Z_]+)(\.r\(\))?\)/\2.downcast::<\1>()/g s/([a-zA-Z]+)Cast::to_ref\(\&?\**([a-zA-Z_]+)(\.[a-zA-Z_]+\(\))?\)/\2\3.downcast::<\1>()/g s/\(([a-zA-Z]+)Cast::to_ref\)/\(Castable::downcast::<\1>\)/g s/([a-zA-Z]+)Cast::to_root/Root::downcast::<\1>/g s/([a-zA-Z]+)Cast::to_layout_js\(&?([a-zA-Z_.]+(\(\))?)\)/\2.downcast::<\1>()/g s/\.is_document\(\)/.is::<Document>()/g s/\.is_htmlanchorelement\(\)/.is::<HTMLAnchorElement>()/g s/\.is_htmlappletelement\(\)/.is::<HTMLAppletElement>()/g s/\.is_htmlareaelement\(\)/.is::<HTMLAreaElement>()/g s/\.is_htmlbodyelement\(\)/.is::<HTMLBodyElement>()/g s/\.is_htmlembedelement\(\)/.is::<HTMLEmbedElement>()/g s/\.is_htmlfieldsetelement\(\)/.is::<HTMLFieldSetElement>()/g s/\.is_htmlformelement\(\)/.is::<HTMLFormElement>()/g s/\.is_htmlframesetelement\(\)/.is::<HTMLFrameSetElement>()/g s/\.is_htmlhtmlelement\(\)/.is::<HTMLHtmlElement>()/g s/\.is_htmlimageelement\(\)/.is::<HTMLImageElement>()/g s/\.is_htmllegendelement\(\)/.is::<HTMLLegendElement>()/g s/\.is_htmloptgroupelement\(\)/.is::<HTMLOptGroupElement>()/g s/\.is_htmloptionelement\(\)/.is::<HTMLOptionElement>()/g s/\.is_htmlscriptelement\(\)/.is::<HTMLScriptElement>()/g s/\.is_htmltabledatacellelement\(\)/.is::<HTMLTableDataCellElement>()/g s/\.is_htmltableheadercellelement\(\)/.is::<HTMLTableHeaderCellElement>()/g s/\.is_htmltablerowelement\(\)/.is::<HTMLTableRowElement>()/g s/\.is_htmltablesectionelement\(\)/.is::<HTMLTableSectionElement>()/g s/\.is_htmltitleelement\(\)/.is::<HTMLTitleElement>()/g
