在Golang中工作，正在尝试使用接口将使用相似方法的一组结构归为一组。简而言之，我有这个：

type Person interface {
    BasicInfo() MemberBasicInfo
}

type MemberBasicInfo struct {
    ID                         uint       
    MemberFirstName            string     
    MemberNickname             string     
    MemberEmail                string    
}

然后，应该用作接口的结构：

func (member *Member) BasicInfo() MemberBasicInfo{
    return MemberBasicInfo{
        ID: member.ID,
        ...other mapping here...
    }
}

func (user *User) BasicInfo() MemberBasicInfo{
    return MemberBasicInfo{
        ID: uint(user.ID),
        ...other mapping here...
    }
}

cannot use memberData (type Member) as type Member.Person in return argument: Member does not implement Person (BasicInfo method has pointer receiver)
cannot use memberData (type User) as type Person in return argument: User does not implement Person (BasicInfo method has pointer receiver)

我想念什么？还是我做错了什么？
