Crate constellation_traits

The interface to the Constellation, which prevents other crates from depending directly on the constellation crate itself. In addition to all messages to the Constellation, this crate is responsible for defining types that cross the process boundary from the embedding/rendering layer all the way to script, thus it should have very minimal dependencies on other parts of Servo.

Modules

• from_script_message 🔒
  Messages send from the ScriptThread to the Constellation.
• structured_data 🔒
  This module contains implementations of structured data as described in https://html.spec.whatwg.org/multipage/#safe-passing-of-structured-data

Structs

• AnimationTickType
  Specifies if rAF should be triggered and/or CSS Animations and Transitions.
• AuxiliaryWebViewCreationRequest
  Specifies the information required to load an auxiliary browsing context.
• AuxiliaryWebViewCreationResponse
  Constellation’s response to auxiliary browsing context creation requests.
• BlobImpl
  The data backing a DOM Blob.
• BroadcastMsg
  Message for communication between the constellation and a global managing broadcast channels.
• DOMMessage
  Message that gets passed to service worker scope on postMessage
• DomException
  A serializable version of the DOMException interface.
• DomPoint
  A serializable version of the DOMPoint/DOMPointReadOnly interface.
• FileBlob
  File-based blob
• 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.
• Job
  https://w3c.github.io/ServiceWorker/#dfn-job
• LoadData
  can be passed to LoadUrl to load a page with GET/POST parameters or headers
• MessagePortImpl
  The data and logic backing the DOM managed MessagePort.
• 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.
• SerializableIter
  An iterator over the variants of Serializable
• StructuredSerializedData
  A data-holder for serialized data and transferred objects. https://html.spec.whatwg.org/multipage/#structuredserializewithtransfer
• TransferrableIter
  An iterator over the variants of Transferrable
• WorkerGlobalScopeInit
  Resources required by workerglobalscopes
• WorkerScriptLoadOrigin
  Common entities representing a network load origin

Enums

• BlobData
  Different backends of Blob
• DocumentState
  Used to determine if a script has any pending asynchronous activity.
• EmbedderToConstellationMessage
  Messages to the Constellation from the embedding layer, whether from ServoRenderer or from libservo itself.
• IFrameSandboxState
  Whether the sandbox attribute is present for an iframe element
• 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.
• 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.
• MessagePortMsg
  Messages for communication between the constellation and a global managing ports.
• NavigationHistoryBehavior
  https://html.spec.whatwg.org/multipage/#navigation-supporting-concepts:navigationhistorybehavior
• PaintMetricEvent
  A description of a paint metric that is sent from the Servo renderer to the constellation.
• SWManagerMsg
  Messages outgoing from the Service Worker Manager thread to constellation
• ScriptToConstellationMessage
  Messages from the script to the constellation.
• Serializable
  All the DOM interfaces that can be serialized.
• ServiceWorkerMsg
  Messages sent to Service Worker Manager thread
• Transferrable
  All the DOM interfaces that can be transferred.
• TraversalDirection
  The direction of a history traversal
• WindowSizeType
  The type of window size change.

Traits

• ServiceWorkerManagerFactory
  This trait allows creating a ServiceWorkerManager without depending on the script crate.
