use Marjask\ObjectValidator\AbstractValidator;
use Marjask\ObjectValidator\Constraints\AlsoRequired;

use Marjask\ObjectValidator\Constraints\Option\OptionAlsoRequired;
use Marjask\ObjectValidator\Constraints\Option\OptionLength;
use Marjask\ObjectValidator\Constraints\Option\OptionType;
use Marjask\ObjectValidator\Constraints\Type;
use Marjask\ObjectValidator\Constraints\TypeOrNull;

final class UserQueryValidator extends AbstractValidator
{
    public function loadConstraints(): void
    {
        $this->addConstraint(
            'username',
            new Type(
                new OptionType('string')
            ),
            new Length(
                new OptionLength(
                    min: 3,
                    max: 16
                )
            )
        )
        ->addConstraint(
            'activated',
            new Type(
                new OptionType('bool')
            ),
            new AlsoRequired(
                new OptionAlsoRequired(['username'])
            )
        )
        ->addConstraint(
            'registerAt',
            new TypeOrNull(
                new OptionType(DateTime::class)
            )
        );
    }
}
```

Usage:

```
$query = (new UserQuery())
    ->setActivated(true)
    ->setUsername('Mariusz')
    ->setRegisterAt(

    );

// return true/false
var_dump(UserQueryValidator::create()->isValid($query));

// return \Marjask\ObjectValidator\ConstraintViolationList
var_dump(UserQueryValidator::create()->getViolations($query));
