Enum UpdateKind 

pub enum UpdateKind {
    Snapshot,
    RealTime,
}

Whether an update carries part of an item’s initial state or a live change.

U carries both: “the notification is also used to send the item’s snapshot” [docs/spec/04-notifications.md §2.1], and telling them apart is a function of four inputs, tabulated in [docs/spec/04-notifications.md §2.4].

Variants

Snapshot

Part of the item’s initial state, delivered because the subscription asked for a snapshot.

A snapshot may be one U (MERGE) or many (DISTINCT, COMMAND), and in the latter case its end is announced by an end-of-snapshot event [docs/spec/04-notifications.md §3.5]. RAW has no snapshot at all.

RealTime

A live change to the item, produced after its initial state.
