Read

Fields

blobs: Option<HashMap<StorageKey, Root<Dom<Blob>>>>

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

message_ports: Option<Vec<Root<Dom<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.

Write

A data holder for transferred and serialized objects.

Fields

ports: Option<HashMap<MessagePortId, MessagePortImpl>>

Transferred ports.

blobs: Option<HashMap<BlobId, BlobImpl>>

Serialized blobs.
