Is it Possible to Add auto-complete in form request classes?

[minaazakii]

If it possible to add something like

` /**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}

public function rules()
{
    return [
        'field_to_validate' => 'required' //List of available rules
    ];
}`
this will be a cool feature if it possible
