For sending timeline markers. Will be ignored if no devtools server

§devtools_marker_sender: DomRefCell<Option<IpcSender<Option<TimelineMarker>>>>§unhandled_resize_event: DomRefCell<Option<(WindowSizeData, WindowSizeType)>>

Most recent unhandled resize event, if any.

§theme: Cell<PrefersColorScheme>

Platform theme.

§parent_info: Option<PipelineId>

Parent id associated with this page, if any.

§dom_static: GlobalStaticData

Global static data related to the DOM.

§js_runtime: DomRefCell<Option<Rc<Runtime>>>

The JavaScript runtime.

§window_size: Cell<WindowSizeData>

The current size of the window, in pixels.

§bluetooth_thread: IpcSender<BluetoothRequest>

A handle for communicating messages to the bluetooth thread.

§bluetooth_extra_permission_data: BluetoothExtraPermissionData§page_clip_rect: Cell<Rect<Au>>

An enlarged rectangle around the page contents visible in the viewport, used to prevent creating display list items for content that is far away from the viewport.

§layout_blocker: Cell<LayoutBlocker>

See the documentation for LayoutBlocker. Essentially, this flag prevents layouts from happening before the first load event, apart from a few exceptional cases.

§webdriver_script_chan: DomRefCell<Option<IpcSender<WebDriverJSResult>>>

A channel for communicating results of async scripts back to the webdriver server

§current_state: Cell<WindowState>

The current state of the window object

§current_viewport: Cell<Rect<Au>>§error_reporter: CSSErrorReporter§scroll_offsets: DomRefCell<HashMap<OpaqueNode, Vector2D<f32, LayoutPixel>>>

A list of scroll offsets for each scrollable element.

§media_query_lists: DOMTracker<MediaQueryList>

All the MediaQueryLists we need to update

§test_runner: MutNullableDom<TestRunner>§webgl_chan: Option<WebGLChan>

A handle for communicating messages to the WebGL thread, if available.

§webxr_registry: Option<Registry>§pending_layout_images: DomRefCell<HashMapTracedValues<PendingImageId, Vec<Dom<Node>>>>

All of the elements that have an outstanding image request that was initiated by layout during a reflow. They are stored in the script thread to ensure that the element can be marked dirty when the image data becomes available at some point in the future.

§unminified_css_dir: DomRefCell<Option<String>>

Directory to store unminified css for this window if unminify-css opt is enabled.

§local_script_source: Option<String>

Directory with stored unminified scripts

§test_worklet: MutNullableDom<Worklet>

Worklets

§paint_worklet: MutNullableDom<Worklet>

https://drafts.css-houdini.org/css-paint-api-1/#paint-worklet

§webrender_document: DocumentId

The Webrender Document id associated with this window.

§exists_mut_observer: Cell<bool>

Flag to identify whether mutation observers are present(true)/absent(false)

§compositor_api: CrossProcessCompositorApi

Cross-process access to the compositor.

§has_sent_idle_message: Cell<bool>

Indicate whether a SetDocumentStatus message has been sent after a reflow is complete. It is used to avoid sending idle message more than once, which is unneccessary.

§relayout_event: bool

Emits notifications when there is a relayout.

§prepare_for_screenshot: bool

True if it is safe to write to the image.

§unminify_css: bool

Unminify Css.

§userscripts_path: Option<String>

Where to load userscripts from, if any. An empty string will load from the resources/user-agent-js directory, and if the option isn’t passed userscripts won’t be loaded.

§replace_surrogates: bool

Replace unpaired surrogates in DOM strings with U+FFFD. See https://github.com/servo/servo/issues/6564

§player_context: WindowGLContext

Window’s GL context from application

§throttled: Cell<bool>§layout_marker: DomRefCell<Rc<Cell<bool>>>

A shared marker for the validity of any cached layout values. A value of true indicates that any such values remain valid; any new layout that invalidates those values will cause the marker to be set to false.

§current_event: DomRefCell<Option<Dom<Event>>>

Struct script::dom::window::WindowCopy item path
