SingleDocumentLiveQueryPublisher

struct SingleDocumentLiveQueryPublisher : Publisher

A Combine publisher that produces a document matching the requested ID, if it can be found.

Warning: Creating a new SingleDocumentLiveQueryPublisher also creates a new Ditto subscription.

It is recommended to keep subscriptions as long-lasting as possible for performance reasons. Instead consider creating a Publisher that operates on device’s own local store and leverage existing subscriptions.
