One field from several should be?

Question

symfony

This example is very old.

It is possible in theory to somehow make a custom constraint or use Callback

Which approach is preferable?
Why?
Perhaps there are some developments?

I'm sure that someone has come across such a validation and there must be developments on the git somewhere.
Better than sculpting on a new one, after all, the case is relatively frequent, it would be possible to add an off validator.

UPD. Wrote a prostelnik method, to whom it is useful. But it is extremely inconvenient to sculpt every time. such a condition can be for more fields in other queries, something else is obviously needed, a constraint.

$classMetadata->addConstraint(new Callback(['callback' => 'validate']));
    }

    public function validate(ExecutionContextInterface $context): void {
        if (true === empty($this->email()) && true === empty($this->apiToken())) {
            $context->buildViolation('one.of.fields.required')
                    ->atPath('email')
                    ->setInvalidValue($this->email())
                    ->addViolation()
            ;
            $context->buildViolation('one.of.fields.required')
                    ->atPath('apiToken')
                    ->setInvalidValue($this->apiToken())
                    ->addViolation()
            ;
        }
    }

I would be grateful for the constraint gist.
