Trait Implementations

impl Castable for HTMLCollection

fn is<T>(&self) -> bool

where T: DerivedFrom<Self>,

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

fn upcast<T>(&self) -> &T

where 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 HTMLCollection

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

fn global(&self) -> Root<Dom<GlobalScope>>

where Self: Sized,

Returns the GlobalScope of the realm that the DomObject was created in. If this object is a Node, this will be different from it’s owning Document if adopted by. For Nodes it’s almost always better to use NodeTraits::owning_global.

impl DomObjectWrap for HTMLCollection

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>, _: CanGc) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::HTMLCollectionBinding::HTMLCollection_Binding::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::htmlcollection::HTMLCollection>, script_runtime::CanGc) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::htmlcollection::HTMLCollection>>}

Function pointer to the general wrap function type

impl HTMLCollectionMethods<DomTypeHolder> for HTMLCollection

fn Length(&self) -> u32

https://dom.spec.whatwg.org/#dom-htmlcollection-length

fn Item(&self, index: u32) -> Option<Root<Dom<Element>>>

https://dom.spec.whatwg.org/#dom-htmlcollection-item

fn NamedItem(&self, key: DOMString) -> Option<Root<Dom<Element>>>

https://dom.spec.whatwg.org/#dom-htmlcollection-nameditem

fn IndexedGetter(&self, index: u32) -> Option<Root<Dom<Element>>>

fn NamedGetter(&self, name: DOMString) -> Option<Root<Dom<Element>>>

fn SupportedPropertyNames(&self) -> Vec<DOMString>

impl HasParent for HTMLCollection

fn as_parent(&self) -> &Reflector

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

type Parent = Reflector

impl IDLInterface for HTMLCollection

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for HTMLCollection

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 HTMLCollection

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

Initializes the Reflector

impl PartialEq for HTMLCollection

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl ToJSValConvertible for HTMLCollection

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

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

impl Traceable for HTMLCollection

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

Trace self.
