    这是一个创建于 696 天前的主题,其中的信息可能已经有所发展或是发生改变。

    如下面,参考了很多项目,都是将 Err 放在最前面如ErrInvalidKey,那么InvalidKeyErr 这样命名有哪里不好? 输入图片说明

    好分类识别、好输入自动补全?
    前缀后缀感觉都差不多,都是为了好识别,让命名有“结构”
    其实在外面再套一层更有结构,"Invalid",“Limit”就成了“前缀”了

    ```
    "Err":{
    InvalidKey = xx
    InvalidValue...
    LimitLength...
    LimitType..
    }
    ```
