9/// A macro to update set values from a data source and handle logging on failure.
10///
11/// This macro encapsulates the logic for:
12/// 1. Calling an `update_set_value` method on a given updater.
13/// 2. On failure, logging the error using a "log-once" pattern.
14/// 3. On success, resetting the "log-once" flag.
