Trait Implementations

impl Castable for HTMLStyleElement

fn is<T>(&self) -> boolwhere
    T: DerivedFrom<Self>,

Check whether a DOM object implements one of its deriving interfaces.

fn upcast<T>(&self) -> &Twhere
    T: Castable,
    Self: DerivedFrom<T>,

Cast a DOM object upwards to one of the interfaces it derives from.

fn downcast<T>(&self) -> Option<&T>where
    T: DerivedFrom<Self>,

Cast a DOM object downwards to one of the interfaces it might implement.

impl DomObject for HTMLStyleElement

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

fn global(&self) -> Root<Dom<GlobalScope>>where
    Self: Sized,

Returns the global scope of the realm that the DomObject was created in.

impl DomObjectWrap for HTMLStyleElement

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::HTMLStyleElementBinding::HTMLStyleElementBinding::Wrap as for<'a, 'b> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::htmlstyleelement::HTMLStyleElement>) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::htmlstyleelement::HTMLStyleElement>>}

Function pointer to the general wrap function type

impl HTMLStyleElementMethods for HTMLStyleElement

fn GetSheet(&self) -> Option<Root<Dom<DOMStyleSheet>>>

impl HasParent for HTMLStyleElement

fn as_parent(&self) -> &HTMLElement

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = HTMLElement

impl IDLInterface for HTMLStyleElement

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl JSTraceable for HTMLStyleElement

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.

impl MallocSizeOf for HTMLStyleElement

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl MutDomObject for HTMLStyleElement

unsafe fn init_reflector(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq<HTMLStyleElement> for HTMLStyleElement

fn eq(&self, other: &HTMLStyleElement) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StylesheetOwner for HTMLStyleElement

fn increment_pending_loads_count(&self)

Notes that a new load is pending to finish.

fn load_finished(&self, succeeded: bool) -> Option<bool>

Returns None if there are still pending loads, or whether any load has failed since the loads started.

fn parser_inserted(&self) -> bool

Returns whether this element was inserted by the parser (i.e., it should trigger a document-load-blocking load).

fn referrer_policy(&self) -> Option<ReferrerPolicy>

Which referrer policy should loads triggered by this owner follow, or None for the default.

fn set_origin_clean(&self, origin_clean: bool)

Sets origin_clean flag.

impl ToJSValConvertible for HTMLStyleElement

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl VirtualMethods for HTMLStyleElement

fn super_type(&self) -> Option<&dyn VirtualMethods>

Returns self as the superclass of the implementation for this trait, if any.

fn children_changed(&self, mutation: &ChildrenMutation<'_>)

Called on the parent when its children are changed.

fn bind_to_tree(&self, context: &BindContext)

Called when a Node is appended to a tree, where ‘tree_connected’ indicates whether the tree is part of a Document.

fn pop(&self)

Called on an element when it is popped off the stack of open elements of a parser.

fn unbind_from_tree(&self, context: &UnbindContext<'_>)

Called when a Node is removed from a tree, where ‘tree_connected’ indicates whether the tree is part of a Document. Implements removing steps: https://dom.spec.whatwg.org/#concept-node-remove-ext

fn attribute_mutated(&self, attr: &Attr, mutation: AttributeMutation<'_>)

Called when attributes of a node are mutated. https://dom.spec.whatwg.org/#attribute-is-set https://dom.spec.whatwg.org/#attribute-is-removed

fn attribute_affects_presentational_hints(&self, attr: &Attr) -> bool

Returns true if given attribute attr affects style of the given element.

fn parse_plain_attribute(&self, name: &LocalName, value: DOMString) -> AttrValue

Returns the right AttrValue variant for the attribute with name name on this element.

fn handle_event(&self, event: &Event)

Called during event dispatch after the bubbling phase completes.

fn adopting_steps(&self, old_doc: &Document)

https://dom.spec.whatwg.org/#concept-node-adopt-ext

fn cloning_steps(
    &self,
    copy: &Node,
    maybe_doc: Option<&Document>,
    clone_children: CloneChildrenFlag
)
