Variants

ChangeRunningAnimationsState(WebViewId, PipelineId, AnimationState)

Alerts the compositor that the given pipeline has changed whether it is running animations.

CreateOrUpdateWebView(SendableFrameTree)

Create or update a webview, given its frame tree.

RemoveWebView(WebViewId)

Remove a webview.

TouchEventProcessed(WebViewId, TouchEventResult)

Script has handled a touch event, and either prevented or allowed default actions.

CreatePng(Option<Rect<f32, CSSPixel>>, IpcSender<Option<Image>>)

Composite to a PNG file and return the Image over a passed channel.

IsReadyToSaveImageReply(bool)

A reply to the compositor asking if the output image is stable.

SetThrottled(WebViewId, PipelineId, bool)

Set whether to use less resources by stopping animations.

NewWebRenderFrameReady(DocumentId, bool)

WebRender has produced a new frame. This message informs the compositor that the frame is ready. It contains a bool to indicate if it needs to composite and the DocumentId of the new frame.

PipelineExited(WebViewId, PipelineId, IpcSender<()>)

A pipeline was shut down.

LoadComplete(WebViewId)

The load of a page has completed

WebDriverMouseButtonEvent(WebViewId, MouseButtonAction, MouseButton, f32, f32)

WebDriver mouse button event

WebDriverMouseMoveEvent(WebViewId, f32, f32)

WebDriver mouse move event

CrossProcess(CrossProcessCompositorMessage)

Messages forwarded to the compositor by the constellation from other crates. These messages are mainly passed on from the compositor to WebRender.
