Crate embedder_traits

Expand description

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.

Structs§

AuthenticationResponse
CompositorHitTestResult: The result of a hit test in the compositor.
DualRumbleEffectParams: https://w3.org/TR/gamepad/#dom-gamepadhapticeffecttype-dual-rumble
EmbedderProxy: Sends messages to the embedder.
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.
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
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.
EmbedderMsg
FormControl
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
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
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.
TouchEventResult: Whether the default action for a touch event was prevented by web content
