Crate script_traits

This module contains traits in script used generically in the rest of Servo. The traits are here instead of in script so that these modules won’t have to depend on script.

Modules

• compositor
  Defines data structures which are consumed by the Compositor.
• script_msg 🔒
• serializable
  This module contains implementations in script that are serializable, as per https://html.spec.whatwg.org/multipage/#serializable-objects. The implementations are here instead of in script so that the other modules involved in the serialization don’t have to depend on script.
• transferable
  This module contains implementations in script that are transferable. The implementations are here instead of in script so that the other modules involved in the transfer don’t have to depend on script.
• webdriver_msg

Structs

• AnimationTickType
  Specifies if rAF should be triggered and/or CSS Animations and Transitions.
• AuxiliaryBrowsingContextLoadInfo
  Specifies the information required to load an auxiliary browsing context.
• BroadcastMsg
  Message for communication between the constellation and a global managing broadcast channels.
• CompositorHitTestResult
  The result of a hit test in the compositor.
• DOMMessage
  Message that gets passed to service worker scope on postMessage
• DrawAPaintImageResult
  The result of executing paint code: the image together with any image URLs that need to be loaded.
• IFrameLoadInfo
  Specifies the information required to load an iframe.
• IFrameLoadInfoWithData
  Specifies the information required to load a URL in an iframe.
• IFrameSizeMsg
  An iframe sizing operation.
• InitialScriptState
  Data needed to construct a script thread.
• InternalBitFlags
• Job
  https://w3c.github.io/ServiceWorker/#dfn-job
• LoadData
  can be passed to LoadUrl to load a page with GET/POST parameters or headers
• NewLayoutInfo
  The initial data required to create a new layout attached to an existing script thread.
• PortMessageTask
  A task on the https://html.spec.whatwg.org/multipage/#port-message-queue
• SWManagerSenders
  Channels to allow service worker manager to communicate with constellation and resource thread
• ScopeThings
  Entities required to spawn service workers
• ScriptToConstellationChan
  A Script to Constellation channel.
• ScrollState
  The scroll state of a stacking context.
• StructuredSerializedData
  A data-holder for serialized data and transferred objects. https://html.spec.whatwg.org/multipage/#structuredserializewithtransfer
• TimerEvent
  Notifies the script thread to fire due timers. TimerSource must be FromWindow when dispatched to ScriptThread and must be FromWorker when dispatched to a DedicatedGlobalWorkerScope
• TimerEventId
  The id to be used for a TimerEvent is defined by the corresponding TimerEventRequest.
• TimerEventRequest
  Requests a TimerEvent-Message be sent after the given duration.
• TimerSchedulerMsg
  The message used to send a request to the timer scheduler.
• TouchId
  An opaque identifier for a touch point.
• UntrustedNodeAddress
  The address of a node. Layout sends these back. They must be validated via from_untrusted_node_address before they can be used, because we do not trust layout.
• WebrenderIpcSender
  A mechanism to communicate with the parent process’ WebRender instance.
• WheelDelta
  The Wheel event deltas in every direction
• WindowSizeData
  Data about the window size.
• WorkerGlobalScopeInit
  Resources required by workerglobalscopes
• WorkerScriptLoadOrigin
  Common entities representing a network load origin

Enums

• AnimationState
  For a given pipeline, whether any animations are currently running and any animation callbacks are queued
• CompositorEvent
  Events from the compositor that the script thread needs to know about
• ConstellationControlMsg
  Messages sent from the constellation or layout to the script thread.
• DiscardBrowsingContext
  When a pipeline is closed, should its browsing context be discarded too?
• DocumentActivity
  Is a document fully active, active or inactive? A document is active if it is the current active document in its session history, it is fuly active if it is active and all of its ancestors are active, and it is inactive otherwise.
• DocumentState
  Used to determine if a script has any pending asynchronous activity.
• EventResult
  Whether a DOM event was prevented by web content
• HistoryEntryReplacement
  https://html.spec.whatwg.org/multipage/#replacement-enabled
• IFrameSandboxState
  Whether the sandbox attribute is present for an iframe element
• ImageUpdate
  Serializable image updates that must be performed by WebRender.
• JobError
  The kind of error the job promise should be rejected with.
• JobResult
  Messages sent from Job algorithms steps running in the SW manager, in order to resolve or reject the job promise.
• JobResultValue
  Jobs are resolved with the help of various values.
• JobType
  https://w3c.github.io/ServiceWorker/#dfn-job-type
• JsEvalResult
  The result of evaluating a javascript scheme url.
• LayoutControlMsg
  Messages sent to the layout thread from the constellation and/or compositor.
• LayoutMsg
  Messages from the layout to the constellation.
• LoadOrigin
  The origin where a given load was initiated. Useful for origin checks, for example before evaluation a JS URL.
• LogEntry
  A log entry reported to the constellation We don’t report all log entries, just serious ones. We need a separate type for this because LogLevel isn’t serializable.
• MediaSessionActionType
  The type of MediaSession action. https://w3c.github.io/mediasession/#enumdef-mediasessionaction
• MessagePortMsg
  Messages for communication between the constellation and a global managing ports.
• Milliseconds
  Unit of measurement.
• MouseButton
  The mouse button involved in the event.
• MouseEventType
  The types of mouse events
• Nanoseconds
  Unit of measurement.
• PaintWorkletError
  Errors from executing a paint worklet
• ProgressiveWebMetricType
  Type of recorded progressive web metric
• SWManagerMsg
  Messages outgoing from the Service Worker Manager thread to constellation
• ScriptMsg
  Messages from the script to the constellation.
• ScriptToCompositorMsg
  The set of WebRender operations that can be initiated by the content process.
• SerializedImageData
  Serialized ImageData. It contains IPC byte channel receiver to prevent from loading bytes too slow.
• SerializedImageUpdate
  Serialized ImageUpdate.
• ServiceWorkerMsg
  Messages sent to Service Worker Manager thread
• TimerSource
  Describes the thread that requested the TimerEvent.
• TouchEventType
  The type of input represented by a multi-touch event.
• UpdatePipelineIdReason
  The reason why the pipeline id of an iframe is being updated.
• WebDriverCommandMsg
