Trait Implementations

impl Castable for MessageEvent

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 MessageEvent

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 MessageEvent

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Box<Self>) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::MessageEventBinding::MessageEventBinding::Wrap as for<'a> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::boxed::Box<dom::messageevent::MessageEvent>) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::messageevent::MessageEvent>>}

Function pointer to the general wrap function type

impl HasParent for MessageEvent

fn as_parent(&self) -> &Event

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

type Parent = Event

impl IDLInterface for MessageEvent

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

Returns whether the given DOM class derives that interface.

impl JSTraceable for MessageEvent

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

Trace self.

impl MallocSizeOf for MessageEvent

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 MessageEventMethods for MessageEvent

fn Data(&self, _cx: JSContext) -> JSVal

https://html.spec.whatwg.org/multipage/#dom-messageevent-data

fn Origin(&self) -> DOMString

https://html.spec.whatwg.org/multipage/#dom-messageevent-origin

fn LastEventId(&self) -> DOMString

https://html.spec.whatwg.org/multipage/#dom-messageevent-lasteventid

fn IsTrusted(&self) -> bool

https://dom.spec.whatwg.org/#dom-event-istrusted

fn Ports(&self, cx: JSContext) -> JSVal

https://html.spec.whatwg.org/multipage/#dom-messageevent-ports

fn InitMessageEvent(
    &self,
    _cx: JSContext,
    type_: DOMString,
    bubbles: bool,
    cancelable: bool,
    data: HandleValue<'_>,
    origin: DOMString,

fn GetSource(&self) -> Option<WindowProxyOrMessagePortOrServiceWorker>

impl MutDomObject for MessageEvent

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

Initializes the Reflector

impl PartialEq<MessageEvent> for MessageEvent

fn eq(&self, other: &MessageEvent) -> 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 ToJSValConvertible for MessageEvent

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

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