Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Notice(DbError)

A notice.

Notices use the same format as errors, but aren’t “errors” per-se.

Notification(Notification)
