英文:
Is there a way to print a string variable in its 2 words format?
问题
我想找到一种清晰的方式来具体地证明一个类型为string的变量保存了一个由两个单词构成的数据结构（至少在我理解的范围内是这样）。
这个演示是为了教学目的。
据我所知，一个字符串是一个由两个单词构成的数据结构，其中一个单词保存了底层字节切片的地址，另一个单词保存了长度。
给定一个像这样定义的变量 a := "a string literal"，有没有一种方式可以查看（或打印）变量的内容以其两个单词的格式，以便人们实际上可以看到这个由两个单词构成的结构？
英文:
I would like to find a clear way to demonstrate concretely that a variable of type string holds a 2-words data structure (at least as far as I understand it).
This demonstration is for didactic purposes.
So, as I know, a string is a 2 words data structure where one word holds the address of the underlying slice of bytes and the word holds the length.
Given a variable defined like this a := "a string literal", is there a way to view (or print) the content of the variable in its 2 words format so that people can actually see this 2-words structure?
答案1
得分: 2
有没有办法以两个单词的格式查看（或打印）变量的内容？
没有，因为这是一个未指定的实现细节。
如果你可以接受可能会出错的代码：可以使用reflect.StringHeader。请参考unsafe.Pointer点（6）上的方法。
最好不要这样做。正如前面所说：这是一个故意隐藏的实现细节。
英文:
> is there a way to view (or print) the content of the variable in its 2 words format?
No, because this is an unspecified implementation detail.
If you are okay with code that might brake: Use reflect.StringHeader. See unsafe.Pointer point (6) on how to do this.
Best not to do this. As said: this is a deliberately hidden implementation detail.
