RowDataPacket constructor

Hello. 
Sorry, if I don't understand how it works.
In d.ts file we have such declaration
```
declare interface RowDataPacket {
    constructor: {
        name: 'RowDataPacket'
    };
    [column: string]: any;
    [column: number]: any;
}
```

But actually RowDataPacket is a binaryRow and thus it has same name in constructor.
thanks
