    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 JSTraceable for PaintWorkletGlobalScope

source§

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

Trace self.
source§

impl MallocSizeOf for PaintWorkletGlobalScope

source§

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

source§

impl MutDomObject for PaintWorkletGlobalScope

source§

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

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<'_>)
