fn replace_worker( &self, new_worker: Option<Trusted<Worker>>, ) -> Option<Trusted<Worker>>

The non-None value of the worker field can contain a rooted TrustedWorkerAddress version of the main thread’s worker object. This is set while handling messages and then unset otherwise, ensuring that the main thread object can be garbage collected. See AutoWorkerReset.

impl DomObject for DedicatedWorkerGlobalScope

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

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.
