## Detailed Description

Identifier for a topic.

Topics are string-based filters that logically group messages together. An implementation may decide to filter different topics on different levels, for example the "protocol" topic may require debug level TRACE while the "core" topic defaults to debug level INFO.

spa_log_topics require a spa_log_methods version of 1 or higher.
