    Writer function for log entries. A log entry is a collection of one or more
    @/GLogFields/@, using the standard <https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html field names from journal
    specification>.
    See @/g_log_structured()/@ for more information.

    Writer functions must ignore fields which they do not recognise, unless they
    can write arbitrary binary output, as field values may be arbitrary binary.

    /@logLevel@/ is guaranteed to be included in /@fields@/ as the @PRIORITY@ field,
    but is provided separately for convenience of deciding whether or where to
    output the log entry.

    Writer functions should return 'GI.GLib.Enums.LogWriterOutputHandled' if they handled the log
    message successfully or if they deliberately ignored it. If there was an
    error handling the message (for example, if the writer function is meant to
    send messages to a remote logging server and there is a network error), it
