There are two provided: -- -- * In the common case: for logging plain text (via 'Utf8Builder') -- efficiently, there is 'LogFunc', which can be created via -- 'withLogFunc', and is accessed via 'HasLogFunc'. This provides -- all the classical logging facilities: timestamped text output -- with log levels and colors (if terminal-supported) to the -- terminal. We log output via 'logInfo', 'logDebug', etc. -- -- * In the advanced case: where logging takes on a more semantic -- meaning and the logs need to be digested, acted upon, translated -- or serialized upstream (to e.g. a JSON logging server), we have -- 'GLogFunc' (as in "generic log function"), and is accessed via -- 'HasGLogFunc'. In this case, we log output via 'glog'. See the -- Type-generic logger section for more information.
