Union and Intersection

UnionType

class UnionType implements Type
{
    /**
     * @param list<Type> $types
     */
    public function __construct(
        public array $types,
    ) {}
}

Direct alternative of native reflection’s ReflectionUnionType. Represents any kind of unions:

• int|string, string|int, string|int|float|bool
• \Generator<string, string>|iterable<string, string>
• string|(\Stringable & object)|(callable(): string)

IntersectionType

class IntersectionType implements Type
{
    /**
     * @param list<Type> $types
     */
    public function __construct(
        public array $types,
    ) {}
}

Direct alternative of native reflection’s ReflectionIntersectionType. Represents any kind of intersections:

• \Stringable & \JsonSerializable
• \IteratorAggregate<string, string> & \ArrayAccess<string, string>
