We had a need to add a callback sink to our logs so we can reprocess log messages to different formats (json and MQTT) while keeping the original logging. I discovered a small trap based on not knowing the C++ standard inside out. To add a sink, be careful how you access sinks() ...

已经有了用于接收前端用户log消息的类logger,代表log消息的类是log_msg,后端写log消息到目标文件的类sink,格式化log消息为最终字符串的类formatter,解析pattern flag的类pattern_formatter等等。但似乎还存在一个问题:库的使用者,如何使用它们? 每次使用时,可能需要先创建logger对象,然后通过logger对象来接收用户log消息。
