fn downcast<T>(&self) -> Option<&T>

where T: DerivedFrom<Self>,

impl DomObject for DedicatedWorkerGlobalScope

type ReflectorType = ()

fn reflector(&self) -> &Reflector<Self::ReflectorType>

Returns the receiver’s reflector.

impl Drop for DedicatedWorkerGlobalScope

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl HasOrigin for DedicatedWorkerGlobalScope

fn origin(&self) -> MutableOrigin

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

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

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