Trait Implementations

impl Castable for WorkletGlobalScope

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.

impl DomObject for WorkletGlobalScope

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for WorkletGlobalScope

const WRAP: unsafe fn(SafeJSContext, &GlobalScope, Option<HandleObject<'_>>, Box<Self>, CanGc) -> Root<Dom<Self>> = {script_bindings::codegen::GenericBindings::WorkletGlobalScopeBinding::Wrap::<dom::bindings::codegen::DomTypeHolder::DomTypeHolder> as for<'a, 'b> unsafe fn(script_bindings::script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::workletglobalscope::WorkletGlobalScope>, script_bindings::script_runtime::CanGc) -> script_bindings::root::Root<script_bindings::root::Dom<dom::workletglobalscope::WorkletGlobalScope>>}

Function pointer to the general wrap function type

impl HasParent for WorkletGlobalScope

fn as_parent(&self) -> &GlobalScope

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

type Parent = GlobalScope

impl IDLInterface for WorkletGlobalScope

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for WorkletGlobalScope

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 WorkletGlobalScope

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

Initializes the Reflector

impl PartialEq for WorkletGlobalScope

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 WorkletGlobalScope

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

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

impl Traceable for WorkletGlobalScope

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

Trace self.
