Expand description

All of the information necessary to create a new [ScriptThread] for a new [EventLoop].

NB: DO NOT add any Senders or Receivers here! pcwalton will have to rewrite your code if you do! Use IPC senders and receivers instead.

Fields§

§id: ScriptEventLoopId

The id of the script event loop that this state will start. This is used to uniquely identify an event loop.

§namespace_request_sender: GenericSender<PipelineNamespaceRequest>

The sender to use to install the Pipeline namespace into this process (if necessary).

§constellation_to_script_sender: GenericSender<ScriptThreadMessage>

A channel with which messages can be sent to us (the script thread).

§constellation_to_script_receiver: GenericReceiver<ScriptThreadMessage>

A port on which messages sent by the constellation to script can be received.

§script_to_constellation_sender: ScriptToConstellationSender

A channel on which messages can be sent to the constellation from script.

§script_to_embedder_sender: ScriptToEmbedderChan

A channel which allows script to send messages directly to the Embedder This will pump the embedder event loop.

§system_font_service: SystemFontServiceProxySender

An IpcSender to the SystemFontService used to create a SystemFontServiceProxy.

§resource_threads: ResourceThreads

A channel to the resource manager thread.

§storage_threads: StorageThreads

A channel to the storage manager thread.

§time_profiler_sender: ProfilerChan

A channel to the time profiler thread.

§memory_profiler_sender: ProfilerChan

A channel to the memory profiler thread.

§devtools_server_sender: Option<GenericCallback<ScriptToDevtoolsControlMsg>>

A channel to the developer tools, if applicable.

§pipeline_namespace_id: PipelineNamespaceId

The ID of the pipeline namespace for this script thread.

§webgl_chan: Option<WebGLPipeline>

A channel to the WebGL thread used in this pipeline.

§webxr_registry: Option<Registry>

The XR device registry

§cross_process_paint_api: CrossProcessPaintApi

Access to Paint across a process boundary.

§player_context: WindowGLContext

Application window’s GL Context for Media player

§privileged_urls: Vec<ServoUrl>

A list of URLs that can access privileged internal APIs.

§user_contents_for_manager_id: FxHashMap<UserContentManagerId, UserContents>

A copy of constellation’s UserContentManagerId to UserContents map.
