impl Castable for PaintWorkletGlobalScope

source§

fn is<T>(&self) -> boolwhere T: DerivedFrom<Self>,

Check whether a DOM object implements one of its deriving interfaces.
source§

fn upcast<T>(&self) -> &Twhere T: Castable, Self: DerivedFrom<T>,

Cast a DOM object upwards to one of the interfaces it derives from.
source§

fn downcast<T>(&self) -> Option<&T>where T: DerivedFrom<Self>,

Cast a DOM object downwards to one of the interfaces it might implement.
source§

impl DomObject for PaintWorkletGlobalScope

source§

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.
source§

fn global(&self) -> Root<Dom<GlobalScope>>where Self: Sized,

Returns the global scope of the realm that the DomObject was created in.
source§

impl HasParent for PaintWorkletGlobalScope

source§

fn as_parent(&self) -> &WorkletGlobalScope

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

§

type Parent = WorkletGlobalScope

source§

impl IDLInterface for PaintWorkletGlobalScope

source§

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

Returns whether the given DOM class derives that interface.
source§

impl MallocSizeOf for PaintWorkletGlobalScope

source§

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.
source§

impl MutDomObject for PaintWorkletGlobalScope

source§

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

Initializes the Reflector
source§

impl PaintWorkletGlobalScopeMethods for PaintWorkletGlobalScope

source§

fn RegisterPaint( &self, name: DOMString, paint_ctor: Rc<VoidFunction> ) -> Result<(), Error>

source§

fn Sleep(&self, ms: u64)

This is a blocking sleep function available in the paint worklet global scope behind the dom.worklet.enabled + dom.worklet.blockingsleep.enabled prefs. It is to be used only for testing, e.g., timeouts, where otherwise one would need busy waiting to make sure a certain timeout is triggered. check-tidy: no specs after this line

source§

impl PartialEq<PaintWorkletGlobalScope> for PaintWorkletGlobalScope

source§

fn eq(&self, other: &PaintWorkletGlobalScope) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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.
source§

impl ToJSValConvertible for PaintWorkletGlobalScope

source§

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

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

impl Traceable for PaintWorkletGlobalScope

source§

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

Trace self.
source§

impl DerivedFrom<EventTarget> for PaintWorkletGlobalScope
