I changed the implementation of writeLogMsg and attached the 
trusted attribute.
Is this a valid solution?

     override void writeLogMsg(ref LogEntry payload) @trusted
     {
		with (payload)
		{
			 writefln(`{"file":"%s", "line":%s, "funcName":"%s", 
"prettyFuncName":"%s",`~
					` "moduleName":"%s", "logLevel":%s, "threadId":%s, 
"timestamp":"%s", "msg":"%s"}`,
				file, line, funcName, prettyFuncName, moduleName, logLevel, 
threadId, timestamp, msg);
			stdout.flush();
		}
     }
