我在代码里直接使用了这个验证包,但是在go.mod里没有引入,代码里ide是不会报错的,因为能找到代码库,但是运行的时候会报错

    However, if an unnamed struct type embeds other types which have methods, then compiler will implicitly The function bodies of the two implicitly declared functions is the same as their corresponding method They can only be declared by compiler implicitly, but they can be called in user code: 1package main By the example above, the Pages method is declared for type Book , so compiler will implicitly declare So for the just mentioned implicitly declared method, the following implicit function is declared by
