Implementations

impl Attr

fn new_inherited( document: &Document, local_name: LocalName, value: AttrValue, name: LocalName, namespace: Namespace, prefix: Option<Prefix>, owner: Option<&Element>, ) -> Attr

pub(crate) fn new( document: &Document, local_name: LocalName, value: AttrValue, name: LocalName, namespace: Namespace, prefix: Option<Prefix>, owner: Option<&Element>, can_gc: CanGc, ) -> DomRoot<Attr>

pub(crate) fn name(&self) -> &LocalName

pub(crate) fn namespace(&self) -> &Namespace

pub(crate) fn prefix(&self) -> Option<&Prefix>

impl Attr

pub(crate) fn set_value(&self, value: AttrValue, owner: &Element, can_gc: CanGc)

pub(crate) fn swap_value(&self, value: &mut AttrValue)

Used to swap the attribute’s value without triggering mutation events

pub(crate) fn identifier(&self) -> &AttrIdentifier

pub(crate) fn value(&self) -> Ref<'_, AttrValue>

pub(crate) fn local_name(&self) -> &LocalName

pub(crate) fn set_owner(&self, owner: Option<&Element>)

Sets the owner element. Should be called after the attribute is added or removed from its older parent.

pub(crate) fn owner(&self) -> Option<DomRoot<Element>>

pub(crate) fn summarize(&self) -> AttrInfo

pub(crate) fn qualified_name(&self) -> DOMString

impl Attr

fn __assert_parent_type(&self)

impl Castable for Attr

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 Attr

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for Attr

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

Function pointer to the general wrap function type

impl HasParent for Attr

fn as_parent(&self) -> &Node

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

type Parent = Node

impl IDLInterface for Attr

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for Attr

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 Attr

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

Initializes the Reflector

impl PartialEq for Attr

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 Attr

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

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

impl Traceable for Attr

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

Trace self.
