EventUpdate

EventUpdate​

enum EventUpdate

An item delivered by a subscription.

A subscription recovers from a lost connection or from falling behind the server on its own, so those interruptions are delivered as updates rather than raised as errors: a caller that does not care about the gap can ignore them and keep reading.

EventUpdate.event(event:)​

case event(event: GraphQlEvent)

EventUpdate.interrupted(message:)​

case interrupted(message: String)

Delivery was interrupted and has recovered — the connection dropped, or the server dropped payloads because this client could not keep up. Items in the gap may have been missed.
