/// `GDtlsConnection` is the base DTLS connection class type, which wraps
/// a [`DatagramBased`][crate::DatagramBased] and provides DTLS encryption on top of it. Its
/// subclasses, [`DtlsClientConnection`][crate::DtlsClientConnection] and
/// [`DtlsServerConnection`][crate::DtlsServerConnection], implement client-side and server-side DTLS,
/// respectively.
///
/// For TLS support, see [`TlsConnection`][crate::TlsConnection].
///
/// As DTLS is datagram based, `GDtlsConnection` implements
/// [`DatagramBased`][crate::DatagramBased], presenting a datagram-socket-like API for the
/// encrypted connection. This operates over a base datagram connection, which is
/// also a `GDatagramBased` ([`base-socket`][struct@crate::DtlsConnection#base-socket]).
///
/// To close a DTLS connection, use [`DtlsConnectionExt::close()`][crate::prelude::DtlsConnectionExt::close()].
///
/// Neither [`DtlsServerConnection`][crate::DtlsServerConnection] or [`DtlsClientConnection`][crate::DtlsClientConnection]
/// set the peer address on their base [`DatagramBased`][crate::DatagramBased] if it is a
/// [`Socket`][crate::Socket] — it is up to the caller to do that if they wish. If they
/// do not, and [`SocketExt::close()`][crate::prelude::SocketExt::close()] is called on the base socket, the
/// `GDtlsConnection` will not raise a `G_IO_ERROR_NOT_CONNECTED` error on
/// further I/O.
///
/// ## Properties
///
///
/// #### `advertised-protocols`
/// The list of application-layer protocols that the connection
/// advertises that it is willing to speak. See
/// g_dtls_connection_set_advertised_protocols().
///
/// Readable | Writeable
///
///
/// #### `base-socket`
/// The #GDatagramBased that the connection wraps. Note that this may be any
/// implementation of #GDatagramBased, not just a #GSocket.
///
/// Readable | Writeable | Construct Only
///
///
/// #### `certificate`
/// The connection's certificate; see
/// g_dtls_connection_set_certificate().
///
/// Readable | Writeable
///
///
/// #### `ciphersuite-name`
/// The name of the DTLS ciphersuite in use. See g_dtls_connection_get_ciphersuite_name().
///
/// Readable
///
///
/// #### `database`
/// The certificate database to use when verifying this TLS connection.
/// If no certificate database is set, then the default database will be
/// used. See g_tls_backend_get_default_database().
///
/// When using a non-default database, #GDtlsConnection must fall back to using
/// the #GTlsDatabase to perform certificate verification using
/// g_tls_database_verify_chain(), which means certificate verification will
/// not be able to make use of TLS session context. This may be less secure.
/// For example, if you create your own #GTlsDatabase that just wraps the
/// default #GTlsDatabase, you might expect that you have not changed anything,
/// but this is not true because you may have altered the behavior of
/// #GDtlsConnection by causing it to use g_tls_database_verify_chain(). See the
/// documentation of g_tls_database_verify_chain() for more details on specific
/// security checks that may not be performed. Accordingly, setting a
/// non-default database is discouraged except for specialty applications with
/// unusual security requirements.
///
/// Readable | Writeable
///
///
/// #### `interaction`
/// A #GTlsInteraction object to be used when the connection or certificate
/// database need to interact with the user. This will be used to prompt the
/// user for passwords where necessary.
///
/// Readable | Writeable
///
///
/// #### `negotiated-protocol`
/// The application-layer protocol negotiated during the TLS
/// handshake. See g_dtls_connection_get_negotiated_protocol().
///
/// Readable
///
///
/// #### `peer-certificate`
/// The connection's peer's certificate, after the TLS handshake has
/// completed or failed. Note in particular that this is not yet set
/// during the emission of #GDtlsConnection::accept-certificate.
///
/// (You can watch for a #GObject::notify signal on this property to
/// detect when a handshake has occurred.)
///
/// Readable
///
///
/// #### `peer-certificate-errors`
/// The errors noticed while verifying
/// #GDtlsConnection:peer-certificate. Normally this should be 0, but
/// it may not be if #GDtlsClientConnection:validation-flags is not
/// [`TlsCertificateFlags::VALIDATE_ALL`][crate::TlsCertificateFlags::VALIDATE_ALL], or if
/// #GDtlsConnection::accept-certificate overrode the default
/// behavior.
///
/// GLib guarantees that if certificate verification fails, at least
/// one error will be set, but it does not guarantee that all possible
/// errors will be set. Accordingly, you may not safely decide to
/// ignore any particular type of error. For example, it would be
/// incorrect to mask [`TlsCertificateFlags::EXPIRED`][crate::TlsCertificateFlags::EXPIRED] if you want to allow
/// expired certificates, because this could potentially be the only
/// error flag set even if other problems exist with the certificate.
///
/// Readable
///
///
/// #### `protocol-version`
/// The DTLS protocol version in use. See g_dtls_connection_get_protocol_version().

/// #### `rehandshake-mode`
/// The rehandshaking mode. See

/// #### `require-close-notify`
/// Whether or not proper TLS close notification is required.

///
/// Readable | Writeable | Construct
///
/// ## Signals
///
///
/// #### `accept-certificate`
/// Emitted during the TLS handshake after the peer certificate has
/// been received. You can examine @peer_cert's certification path by
/// calling g_tls_certificate_get_issuer() on it.
///
/// For a client-side connection, @peer_cert is the server's
/// certificate, and the signal will only be emitted if the
/// certificate was not acceptable according to @conn's
/// #GDtlsClientConnection:validation_flags. If you would like the
/// certificate to be accepted despite @errors, return [`true`] from the
/// signal handler. Otherwise, if no handler accepts the certificate,
/// the handshake will fail with [`TlsError::BadCertificate`][crate::TlsError::BadCertificate].
///
/// GLib guarantees that if certificate verification fails, this signal
/// will be emitted with at least one error will be set in @errors, but
/// it does not guarantee that all possible errors will be set.
/// Accordingly, you may not safely decide to ignore any particular
/// type of error. For example, it would be incorrect to ignore
/// [`TlsCertificateFlags::EXPIRED`][crate::TlsCertificateFlags::EXPIRED] if you want to allow expired
/// certificates, because this could potentially be the only error flag
/// set even if other problems exist with the certificate.
///
/// For a server-side connection, @peer_cert is the certificate
/// presented by the client, if this was requested via the server's
/// #GDtlsServerConnection:authentication_mode. On the server side,
/// the signal is always emitted when the client presents a
/// certificate, and the certificate will only be accepted if a
/// handler returns [`true`].
///
/// Note that if this signal is emitted as part of asynchronous I/O
/// in the main thread, then you should not attempt to interact with
