Expand description

Messages sent from the constellation or layout to the script thread.

Variants§

§

StopDelayingLoadEventsMode(PipelineId)

Takes the associated window proxy out of “delaying-load-events-mode”, used if a scheduled navigated was refused by the embedder. https://html.spec.whatwg.org/multipage/#delaying-load-events-mode

§

NavigationResponse(PipelineId, FetchResponseMsg)

Sends the final response to script thread for fetching after all redirections have been resolved

§

AttachLayout(NewLayoutInfo)

Gives a channel and ID to a layout, as well as the ID of that layout’s parent

§

Resize(PipelineId, WindowSizeData, WindowSizeType)

Window resized. Sends a DOM event eventually, but first we combine events.

§

ResizeInactive(PipelineId, WindowSizeData)

Notifies script that window has been resized but to not take immediate action.

§

ExitFullScreen(PipelineId)

Window switched from fullscreen mode.

§

UnloadDocument(PipelineId)

Notifies the script that the document associated with this pipeline should ‘unload’.

§

ExitPipeline(PipelineId, DiscardBrowsingContext)

Notifies the script that a pipeline should be closed.

§

ExitScriptThread

Notifies the script that the whole thread should be closed.

§

SendEvent(PipelineId, CompositorEvent)

Sends a DOM event.

§

Viewport(PipelineId, Rect<f32, UnknownUnit>)

Notifies script of the viewport.

§

GetTitle(PipelineId)

Requests that the script thread immediately send the constellation the title of a pipeline.

§

SetDocumentActivity(PipelineId, DocumentActivity)

Notifies script thread of a change to one of its document’s activity

§

SetThrottled(PipelineId, bool)

Set whether to use less resources by running timers at a heavily limited rate.

§

SetThrottledInContainingIframe(PipelineId, BrowsingContextId, bool)

Notify the containing iframe (in PipelineId) that the nested browsing context (BrowsingContextId) is throttled.

§

NavigateIframe(PipelineId, BrowsingContextId, LoadData, HistoryEntryReplacement)

Notifies script thread that a url should be loaded in this iframe. PipelineId is for the parent, BrowsingContextId is for the nested browsing context

§

PostMessage

Fields

§target: PipelineId

The target of the message.

§source: PipelineId

The source of the message.

§source_browsing_context: TopLevelBrowsingContextId

The top level browsing context associated with the source pipeline.

§target_origin: Option<ImmutableOrigin>

The expected origin of the target.

§data: StructuredSerializedData

The data to be posted.

Post a message to a given window.

§

UpdatePipelineId(PipelineId, BrowsingContextId, TopLevelBrowsingContextId, PipelineId, UpdatePipelineIdReason)

Updates the current pipeline ID of a given iframe. First PipelineId is for the parent, second is the new PipelineId for the frame.

§

UpdateHistoryState(PipelineId, Option<HistoryStateId>, ServoUrl)

Updates the history state and url of a given pipeline.

§

RemoveHistoryStates(PipelineId, Vec<HistoryStateId>)

Removes inaccesible history states.

§

FocusIFrame(PipelineId, BrowsingContextId)

Set an iframe to be focused. Used when an element in an iframe gains focus. PipelineId is for the parent, BrowsingContextId is for the nested browsing context

§

WebDriverScriptCommand(PipelineId, WebDriverScriptCommand)

Passes a webdriver command to the script thread for execution

§

TickAllAnimations(PipelineId, AnimationTickType)

Notifies script thread that all animations are done

§

WebFontLoaded(PipelineId, bool)

Notifies the script thread that a new Web font has been loaded, and thus the page should be reflowed.

§

DispatchIFrameLoadEvent

Fields

§target: BrowsingContextId

The frame that has been marked as loaded.

§parent: PipelineId

The pipeline that contains a frame loading the target pipeline.

§child: PipelineId

The pipeline that has completed loading.

Cause a load event to be dispatched at the appropriate iframe element.

§

DispatchStorageEvent(PipelineId, StorageType, ServoUrl, Option<String>, Option<String>, Option<String>)

Cause a storage event to be dispatched at the appropriate window. The strings are key, old value and new value.

§

ReportCSSError(PipelineId, String, u32, u32, String)

Report an error from a CSS parser for the given pipeline

§

Reload(PipelineId)

Reload the given page.

§

PaintMetric(PipelineId, ProgressiveWebMetricType, u64)

Notifies the script thread about a new recorded paint metric.

§

MediaSessionAction(PipelineId, MediaSessionActionType)

Notifies the media session about a user requested media session action.

§

SetWebGPUPort(IpcReceiver<WebGPUMsg>)

Notifies script thread that WebGPU server has started

§

SetScrollStates(PipelineId, Vec<ScrollState>)

The compositor scrolled and is updating the scroll states of the nodes in the given pipeline via the Constellation.

§

SetEpochPaintTime(PipelineId, Epoch, u64)

Send the paint time for a specific epoch.
