golang在嵌套结构中初始化内部结构对象

Question

I have a nested struct

type Posts struct {
    Id        int
    CreatedAt time.Time
    Data      struct {
        Title    string
        UserName string
    }
}

I want to create a Data object but var innerData Posts.Data doesn't seem to work. I don't want to create separate Data struct because I'm planning to avoid name collusions by having multiple structs which will have different inner structs named Data.

Answer 1

You can't. Posts.Data isn't the name of a type. The only thing you could do is var innerData struct{ ... }, which I'm sure you don't want to because then you would have repetition and need to make changes in two places. Otherwise, you have to give it a name. That name doesn't have to be Data, it can be PostData or something to make it unique.
