Crate embedder_traits 

Types used by the embedding layer and/or exposed to the API. 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. If a type is not exposed in the API or doesn’t involve messages sent to the embedding/libservo layer, it is probably a better fit for the constellation_traits crate.

Modules

Structs

AuthenticationResponse

CompositorHitTestResult

The result of a hit test in the compositor.

DualRumbleEffectParams

https://w3.org/TR/gamepad/#dom-gamepadhapticeffecttype-dual-rumble

EmbedderControlId

EmbedderProxy

Sends messages to the embedder.

FilePickerRequest

FilterPattern

Filter for file selection; the String content is expected to be extension (e.g, “doc”, without the prefixing “.”)

FocusSequenceNumber

A sequence number generated by a script thread for its pipelines. The constellation attaches the target pipeline’s last seen FocusSequenceNumber to every focus-related message it sends.

Image

A raster image buffer.

InputMethodRequest

Request to present an IME to the user when an editable element is focused. If type is InputMethodType::Text, then the text parameter specifies the pre-existing text content and insertion_point the zero-based index into the string of the insertion point.

JavaScriptErrorInfo

JavaScriptEvaluationId

An identifier for a particular JavaScript evaluation that is used to track the evaluation from the embedding layer to the script layer and then back.

MediaMetadata

https://w3c.github.io/mediasession/#mediametadata

MediaPositionState

https://w3c.github.io/mediasession/#dictdef-mediapositionstate

Notification

Data that could be used to display a desktop notification to the end user when the Notification API is called.

NotificationAction

Actions available for users to choose from for interacting with the notification.

RgbColor

ScreenGeometry

Information about a WebView’s screen geometry and offset. This is used for the Screen CSSOM APIs and window.screenLeft / window.screenX / window.screenTop / window.screenY / window.moveBy/ window.resizeBy / window.outerWidth / window.outerHeight / window.screen.availHeight / window.screen.availWidth.

ScreenMetrics

Unlike ScreenGeometry, the data is in device-independent pixels to be used by DOM APIs

ScriptToEmbedderChan

A Script to Embedder Channel

SelectElementOption

SelectedFile

Response to file selection request

TraversalId

An opaque identifier for a single history traversal operation.

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.

ViewportDetails

Data about a WebView or <iframe> viewport: its size and also the HiDPI scale factor to use when rendering the contents.

WebResourceRequest

WebResourceResponse

Enums

AlertResponse

AllowOrDeny

A response to a request to allow or deny an action.

AnimationState

For a given pipeline, whether any animations are currently running and any animation callbacks are queued

ConfirmResponse

ContextMenuResult

Cursor

A cursor for the window. This is different from a CSS cursor (see CursorKind) in that it has no Auto value.

EmbedderControlRequest

EmbedderControlResponse

EmbedderMsg

GamepadHapticEffectType

https://w3.org/TR/gamepad/#dom-gamepadhapticeffecttype

InputMethodType

Used to specify the kind of input method editor appropriate to edit a field. This is a subset of htmlinputelement::InputType because some variants of InputType don’t make sense in this context.

JSValue

JavaScriptEvaluationError

An error that happens when trying to evaluate JavaScript on a WebView.

JavaScriptEvaluationResultSerializationError

Indicates the reason that JavaScript evaluation failed due serializing issues the result of the evaluation.

LoadStatus

The status of the load in this WebView.

MediaSessionActionType

https://w3c.github.io/mediasession/#enumdef-mediasessionaction

MediaSessionEvent

Type of events sent from script to the embedder about the media session.

MediaSessionPlaybackState

https://w3c.github.io/mediasession/#enumdef-mediasessionplaybackstate

PermissionFeature

Enum with variants that match the DOM PermissionName enum

PixelFormat

PromptResponse

ScreenshotCaptureError

Scroll

SelectElementOptionOrOptgroup

Represents the contents of either an <option> or an <optgroup> element

ShutdownState

Tracks whether Servo isn’t shutting down, is in the process of shutting down, or has finished shutting down.

SimpleDialog

Simple dialogs are synchronous dialogs that can be opened by web content. Since their messages are controlled by web content, they should be presented to the user in a way that makes them impossible to mistake for browser UI.

Theme

The type of platform theme.

WebResourceResponseMsg

WebViewPoint

A point in a WebView, either expressed in device pixels or page pixels. Page pixels are CSS pixels, which take into account device pixel scale, page zoom, and pinch zoom.

WebViewRect

A rectangle in a WebView, either expressed in device pixels or page pixels. Page pixels are CSS pixels, which take into account device pixel scale, page zoom, and pinch zoom.

WebViewVector

Traits

EventLoopWaker

RefreshDriver

A RefreshDriver is a trait that can be implemented by Servo embedders in order to drive let Servo know when to start preparing the next frame. For example, on systems that support Vsync notifications, an embedder may want to implement this trait to drive Servo animations via those notifications.
