Fields

errors: DOMErrorRecord

A struct of error message.

blobs: Option<HashMap<StorageKey, DomRoot<Blob>>>

A map of deserialized blobs, stored temporarily here to keep them rooted.

points_read_only: Option<HashMap<StorageKey, DomRoot<DOMPointReadOnly>>>

A map of deserialized points, stored temporarily here to keep them rooted.

dom_points: Option<HashMap<StorageKey, DomRoot<DOMPoint>>>

message_ports: Option<Vec<DomRoot<MessagePort>>>

A vec of transfer-received DOM ports, to be made available to script through a message event.

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.

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.
