1592 * QUIC integration.
1593 *
1594 * QUIC acts as an underlying transport for the TLS 1.3 handshake. The following
1595 * functions allow a QUIC implementation to serve as the underlying transport as
1596 * described in RFC 9001.
1597 *
1598 * When configured for QUIC, |SSL_do_handshake| will drive the handshake as
1599 * before, but it will not use the configured |BIO|. It will call functions on
1600 * |SSL_QUIC_METHOD| to configure secrets and send data. If data is needed from
1601 * the peer, it will return |SSL_ERROR_WANT_READ|. As the caller receives data
1602 * it can decrypt, it calls |SSL_provide_quic_data|. Subsequent
1603 * |SSL_do_handshake| calls will then consume that data and progress the
1604 * handshake. After the handshake is complete, the caller should continue to
1605 * call |SSL_provide_quic_data| for any post-handshake data, followed by
1606 * |SSL_process_quic_post_handshake| to process it. It is an error to call
1607 * |SSL_peek|, |SSL_read| and |SSL_write| in QUIC.
1608 *
1609 * To avoid DoS attacks, the QUIC implementation must limit the amount of data
1610 * being queued up. The implementation can call
1611 * |SSL_quic_max_handshake_flight_len| to get the maximum buffer length at each
1612 * encryption level.
1613 *
1614 * QUIC implementations must additionally configure transport parameters with
1615 * |SSL_set_quic_transport_params|. |SSL_get_peer_quic_transport_params| may be
1616 * used to query the value received from the peer. This extension is handled
1617 * as an opaque byte string, which the caller is responsible for serializing
1618 * and parsing. See RFC 9000 section 7.4 for further details.
