The type that is returned when calling observe_local on a PendingCursorOperation object. It handles the logic for calling the EventHandler that is provided to observe_local calls. LiveQuery objects must be kept in scope for as long as you wish to have your event handler be called when there is an update to a document matching the query you provide.

query: Box

collection_name: Box

subscription: Option<Box<Subscription>>
