Trait Implementations

impl Castable for DedicatedWorkerGlobalScope

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.

fn PostMessage( &self, cx: SafeJSContext, message: HandleValue<'_>, transfer: CustomAutoRooterGuard<'_, Vec<*mut JSObject>>, ) -> Result<(), Error>

https://html.spec.whatwg.org/multipage/#dom-dedicatedworkerglobalscope-postmessage

fn PostMessage_( &self, cx: SafeJSContext, message: HandleValue<'_>, options: RootedTraceableBox<StructuredSerializeOptions>, ) -> Result<(), Error>

https://html.spec.whatwg.org/multipage/#dom-dedicatedworkerglobalscope-postmessage

fn Close(&self)

fn GetOnmessage(&self) -> Option<Rc<EventHandlerNonNull>>

fn SetOnmessage(&self, listener: Option<Rc<EventHandlerNonNull>>)

impl DomObject for DedicatedWorkerGlobalScope

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 HasParent for DedicatedWorkerGlobalScope

fn as_parent(&self) -> &WorkerGlobalScope

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

type Parent = WorkerGlobalScope

impl IDLInterface for DedicatedWorkerGlobalScope

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for DedicatedWorkerGlobalScope

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 DedicatedWorkerGlobalScope

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

Initializes the Reflector

impl PartialEq for DedicatedWorkerGlobalScope

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 DedicatedWorkerGlobalScope

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

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

impl Traceable for DedicatedWorkerGlobalScope

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

Trace self.
