Enum Array

[aiglesiasn]

Hi @frankdejonge thank you for your great package!
I wanted to ask you something.
I wanted to hydrate an Object that has an array of Enums.

enum Role: string {
    case ADMIN = "administrator";
    case USER = "user";
}

class Object {
  public function __construct(
    /**
     *
     * @var Role[]|null $role
    **/
    #[CastListToType(Role::class)]
    private ?array $role
    ){}
}

I tried with CastListToType Attribute but this didn't work because I got and exception: Argument #2 ($payload) must be of type array, string given

I ended up creating this caster for Enums:

use Attribute;
use EventSauce\ObjectHydrator\ObjectMapper;
use EventSauce\ObjectHydrator\PropertyCaster;

#[Attribute(Attribute::TARGET_PARAMETER)]
class CastListToEnum implements PropertyCaster
{
    public function __construct(
        public string $enumName
    ) {}

    public function cast(mixed $value, ObjectMapper $hydrator) : mixed
    {
        foreach ($value as $i => $item) {
            if (enum_exists($this->enumName)) {
                $value[$i] = $this->enumName::from($item);
            } else {
                $value[$i] = $item;
            }
        }

        return $value;
  

And this worked.

What do you think about this? do you see any other solution for this case?
Thanks for your time!
