ObjectValidator

Use ObjectValidator when one DTO contains another DTO or domain object.

Create a rule

Rule::object(string $field, string $targetClass): ObjectValidator

Methods

Method	Description
`required(bool $required = true)`	Require the nested object.
`optional()`	Allow the nested object to be missing.
`isRequired(bool $required = true)`	Set requiredness explicitly.
`requiredState()`	Read the current requiredness.

Example

use Fynix\RuleSet;

ValidationRegistry::register(User::class, static fn (RuleSet $rules): array => [
    $rules->object('address', Address::class),
]);

The nested class must have rules registered with ValidationRegistry. Fynix verifies the object type and then delegates validation to that class’s rules.
