What is Hibernate 7's @Struct mapping for database composite types?

import org.hibernate.annotations.Struct;

@Embeddable
@Struct(name="address_type")  // maps to the DB composite type
public record AddressType(
    String street,
    String city,
    String postcode,
    String countryCode
) {}

@Entity
public class Customer {
    @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id;
    private String name;

    @Column(name="shipping_address")  // single column of type address_type!
    private AddressType shippingAddress;
}

// PostgreSQL DDL:
// CREATE TYPE address_type AS (
//   street       VARCHAR(255),
//   city         VARCHAR(100),
//   postcode     VARCHAR(10),
//   country_code VARCHAR(2)
// );
// CREATE TABLE customer (
//   id               BIGINT PRIMARY KEY,
//   name             VARCHAR(255),
//   shipping_address address_type  -- single composite column!
// );

// HQL querying the struct:
List<Customer> london = session
    .createQuery("FROM Customer c WHERE c.shippingAddress.city = :city", Customer.class)
    .setParameter("city", "London").getResultList();
// Generated: WHERE (shipping_address).city = 'London'
