英文:
Go equivalent of a void pointer in C
问题
我一直在尝试使用Go语言制作一些数据结构库，但是遇到了一个大问题。我希望数据结构能够容纳任何类型，但是在Go语言中我没有找到任何方法来实现这一点，因为无法声明空指针，也没有类似于NSObject的所有类的继承关系。在Go语言中，我应该如何实现相同的功能呢？
英文:
I've been playing around with Go a little bit making some data structure libraries and I have one big problem. I want the data structure to be able to contain any type, but I don't see any way to do this in Go because you can't declare void pointers and they don't have a class like NSObject that everything inherits from. How would I achieve this same functionality in Go?

根据Go编程语言规范：
> 一个类型实现了包含其方法的任何子集的任何接口，因此可以实现多个不同的接口。例如，所有类型都实现了空接口：<pre>interface{}</pre>
如果你在该文档中搜索interface{}，你会看到很多例子，说明你可以使用它来实现你想要的功能。
英文:
According to the Go Programming Language Specification:
> A type implements any interface comprising any subset of its methods and may therefore implement several distinct interfaces. For instance, all types implement the empty interface: <pre>interface{}</pre>
If you search within that document for interface{}, you'll see quite a few examples of how you can use it to do what you want.
