Expand description

The set of WebRender operations that can be initiated by the content process.

Variants§

SendInitialTransaction(PipelineId)

Inform WebRender of the existence of this pipeline.

SendScrollNode(PipelineId, LayoutPoint, ExternalScrollId)

Perform a scroll operation.

SendDisplayList

Inform WebRender of a new display list for the given pipeline.

Fields

§display_list_info: CompositorDisplayListInfo

The CompositorDisplayListInfo that describes the display list being sent.

§display_list_descriptor: BuiltDisplayListDescriptor

A descriptor of this display list used to construct this display list from raw data.

§display_list_receiver: IpcBytesReceiver

An ipc::IpcBytesReceiver used to send the raw data of the display list.

HitTest(Option<PipelineId>, DevicePoint, HitTestFlags, IpcSender<Vec<CompositorHitTestResult>>)

Perform a hit test operation. The result will be returned via the provided channel sender.

GenerateImageKey(IpcSender<ImageKey>)

Create a new image key. The result will be returned via the provided channel sender.

UpdateImages(Vec<SerializedImageUpdate>)

Perform a resource update operation.

RemoveFonts(Vec<FontKey>, Vec<FontInstanceKey>)

Remove the given font resources from our WebRender instance.
