Crate script_traitssource ·
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.
Defines data structures which are consumed by the Compositor.
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.
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.
Specifies if rAF should be triggered and/or CSS Animations and Transitions.
Specifies the information required to load an auxiliary browsing context.
Message for communication between the constellation and a global managing broadcast channels.
The result of a hit test in the compositor.
Message that gets passed to service worker scope on postMessage
The result of executing paint code: the image together with any image URLs that need to be loaded.
Specifies the information required to load an iframe.
Specifies the information required to load a URL in an iframe.
An iframe sizing operation.

Requests a TimerEvent-Message be sent after the given duration.
The message used to send a request to the timer scheduler.
An opaque identifier for a touch point.
The address of a node. Layout sends these back. They must be validated via
from_untrusted_node_addressbefore they can be used, because we do not trust layout.
A mechanism to communicate with the parent process’ WebRender instance.
The Wheel event deltas in every direction
Data about the window size.
Resources required by workerglobalscopes
Common entities representing a network load origin
For a given pipeline, whether any animations are currently running and any animation callbacks are queued
Events from the compositor that the script thread needs to know about
Messages sent from the constellation or layout to the script thread.
When a pipeline is closed, should its browsing context be discarded too?
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.
Used to determine if a script has any pending asynchronous activity.
Whether a DOM event was prevented by web content
Whether the sandbox attribute is present for an iframe element
Serializable image updates that must be performed by WebRender.
The kind of error the job promise should be rejected with.
Messages sent from Job algorithms steps running in the SW manager, in order to resolve or reject the job promise.
Jobs are resolved with the help of various values.
Messages sent to the layout thread from the constellation and/or compositor.
Messages from the layout to the constellation.
The origin where a given load was initiated. Useful for origin checks, for example before evaluation a JS URL.
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
