Fields

error: Option<Error>

A error record.

roots: RootedVec<'a, Box<Heap<*mut JSObject>>>

Rooted copies of every deserialized object to ensure they are not garbage collected.

port_impls: Option<HashMap<MessagePortId, MessagePortImpl>>

A map of port implementations, used as part of the “transfer-receiving” steps of ports, to produce the DOM ports stored in message_ports above.

transform_streams_port_impls: Option<HashMap<MessagePortId, TransformStreamData>>

A map of transform stream implementations,

blob_impls: Option<HashMap<BlobId, BlobImpl>>

A map of blob implementations, used as part of the “deserialize” steps of blobs, to produce the DOM blobs stored in blobs above.

points: Option<HashMap<DomPointId, DomPoint>>

A map of serialized points.

rects: Option<HashMap<DomRectId, DomRect>>

A map of serialized rects.

quads: Option<HashMap<DomQuadId, DomQuad>>

A map of serialized quads.

matrices: Option<HashMap<DomMatrixId, DomMatrix>>

A map of serialized matrices.

exceptions: Option<HashMap<DomExceptionId, DomException>>

A map of serialized exceptions.

quota_exceeded_errors: Option<HashMap<QuotaExceededErrorId, SerializableQuotaExceededError>>

A map of serialized quota exceeded errors.

image_bitmaps: Option<HashMap<ImageBitmapId, SerializableImageBitmap>>

transferred_image_bitmaps: Option<HashMap<ImageBitmapId, SerializableImageBitmap>>

A map of transferred image bitmaps.

offscreen_canvases: Option<HashMap<OffscreenCanvasId, TransferableOffscreenCanvas>>

A map of transferred offscreen canvases.
