Trait Implementations§

source §

impl Castable for EventTarget

source §

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

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

source §

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

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

source §

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

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

source §

impl DomObject for EventTarget

source §

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

source §

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

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

source §

impl DomObjectWrap for EventTarget

source §

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::EventTargetBinding::EventTarget_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::eventtarget::EventTarget>) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::eventtarget::EventTarget>>}

Function pointer to the general wrap function type

source §

impl EventTargetMethods for EventTarget

source §

fn AddEventListener( &self, ty: DOMString, listener: Option<Rc<EventListener>>, options: AddEventListenerOptionsOrBoolean )

source §

fn RemoveEventListener( &self, ty: DOMString, listener: Option<Rc<EventListener>>, options: EventListenerOptionsOrBoolean )

source §

fn DispatchEvent(&self, event: &Event) -> Result<bool, Error>

source §

impl HasParent for EventTarget

source §

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

source §

impl IDLInterface for EventTarget

source §

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

Returns whether the given DOM class derives that interface.

source §

impl MallocSizeOf for EventTarget

source §

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.

source §

impl MutDomObject for EventTarget

source §

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

Initializes the Reflector

source §

impl PartialEq<EventTarget> for EventTarget

source §

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

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

1.0.0 · source§

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.

source §

impl ToJSValConvertible for EventTarget

source §

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

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

source §

impl Traceable for EventTarget

source §

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

Trace self.

source §

impl VirtualMethods for EventTarget

source §

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

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

source §

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

source §

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

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

source §

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

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

source §

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.

source §

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
