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: Box<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.

AddImage(ImageKey, ImageDescriptor, SerializableImageData)

Add an image with the given data and ImageKey.

UpdateImages(Vec<ImageUpdate>)

Perform a resource update operation.

GenerateFontKeys(usize, usize, IpcSender<(Vec<FontKey>, Vec<FontInstanceKey>)>)

Generate a new batch of font keys which can be used to allocate keys asynchronously.

AddFont(FontKey, Arc<IpcSharedMemory>, u32)

Add a font with the given data and font key.

AddSystemFont(FontKey, NativeFontHandle)

Add a system font with the given font key and handle.

AddFontInstance(FontInstanceKey, FontKey, f32, FontInstanceFlags)

Add an instance of a font with the given instance key.

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

Remove the given font resources from our WebRender instance.

GetClientWindowRect(IpcSender<DeviceIntRect>)

Get the client window size and position.

GetScreenSize(IpcSender<DeviceIntSize>)

Get the size of the screen that the client window inhabits.

GetAvailableScreenSize(IpcSender<DeviceIntSize>)

Get the available screen size (without toolbars and docks) for the screen the client window inhabits.
