// Represents an IndexedDB Object Store value retrieved from the backing store.
//
// For most purposes, the backing store represents each IndexedDB value as wire
// data (a vector of bytes produced by SerializedScriptValue) and attached Blobs
// (a vector of Blobs).
//
// Object stores with auto-incrementing primary keys are a special case. To
// guarantee that we generate unique sequential numbers, the primary keys for
// these values are generated by the backing store. In this case, the primary
// key must be stored along the wire data. The backing store cannot invoke
// SerializedScriptValue, so it cannot inject the primary key into the wire
// bytes. Instead, when the values are read, Blink receives the primary keys
// along the IndexedDB values, and is responsible for injecting the keys into
// the values before returning them to the user.
