| CancelAnimationFrame(uint) | https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#animationframeprovider-cancelanimationframe |
| Close() | Closes the worker: its event loop ends once the running task completes (https://html.spec.whatwg.org/multipage/workers.html#dom-dedicatedworkerglobalscope-close). |
| PostMessage(object?, StructuredSerializeOptions?) | Posts a message to the Worker object (https://html.spec.whatwg.org/multipage/workers.html#dom-dedicatedworkerglobalscope-postmessage-options). |
| PostMessage(object?, IReadOnlyList<object>) | Posts a message to the Worker object (https://html.spec.whatwg.org/multipage/workers.html#dom-dedicatedworkerglobalscope-postmessage). |
| RequestAnimationFrame(FrameRequestCallback) | https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#dom-animationframeprovider-requestanimationframe: runs the callback at the next frame of the worker. There is no rendering: the frames run at a fixed rate (60 frames per second) measured with DomEventLoop.TimeProvider. |
