/// [`TlsConnection`][crate::TlsConnection] is the base TLS connection class type, which wraps
/// a [`IOStream`][crate::IOStream] and provides TLS encryption on top of it. Its
/// subclasses, [`TlsClientConnection`][crate::TlsClientConnection] and [`TlsServerConnection`][crate::TlsServerConnection],
/// implement client-side and server-side TLS, respectively.
///
/// For DTLS (Datagram TLS) support, see `GDtlsConnection`.
///
/// This is an Abstract Base Class, you cannot instantiate it.
///
/// ## Properties
///
///
/// #### `advertised-protocols`
/// The list of application-layer protocols that the connection
/// advertises that it is willing to speak. See
/// [`TlsConnectionExtManual::set_advertised_protocols()`][crate::prelude::TlsConnectionExtManual::set_advertised_protocols()].
///
/// Readable | Writeable
///
///
/// #### `base-io-stream`
/// The [`IOStream`][crate::IOStream] that the connection wraps. The connection holds a reference
/// to this stream, and may run operations on the stream from other threads
/// throughout its lifetime. Consequently, after the [`IOStream`][crate::IOStream] has been
/// constructed, application code may only run its own operations on this
/// stream when no [`IOStream`][crate::IOStream] operations are running.
///
/// Readable | Writeable | Construct Only
///
///
/// #### `certificate`
/// The connection's certificate; see
/// [`TlsConnectionExt::set_certificate()`][crate::prelude::TlsConnectionExt::set_certificate()].
///
/// Readable | Writeable
///
///
/// #### `ciphersuite-name`
/// The name of the TLS ciphersuite in use. See [`TlsConnectionExt::ciphersuite_name()`][crate::prelude::TlsConnectionExt::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 [`TlsBackendExt::default_database()`][crate::prelude::TlsBackendExt::default_database()].
///
/// When using a non-default database, [`TlsConnection`][crate::TlsConnection] must fall back to using
/// the [`TlsDatabase`][crate::TlsDatabase] to perform certificate verification using
/// [`TlsDatabaseExt::verify_chain()`][crate::prelude::TlsDatabaseExt::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 [`TlsDatabase`][crate::TlsDatabase] that just wraps the
/// default [`TlsDatabase`][crate::TlsDatabase], you might expect that you have not changed anything,
/// but this is not true because you may have altered the behavior of
/// [`TlsConnection`][crate::TlsConnection] by causing it to use [`TlsDatabaseExt::verify_chain()`][crate::prelude::TlsDatabaseExt::verify_chain()]. See the
/// documentation of [`TlsDatabaseExt::verify_chain()`][crate::prelude::TlsDatabaseExt::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 [`TlsInteraction`][crate::TlsInteraction] 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 [`TlsConnectionExt::negotiated_protocol()`][crate::prelude::TlsConnectionExt::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 [`accept-certificate`][struct@crate::TlsConnection#accept-certificate].
///
/// (You can watch for a [`notify`][struct@crate::glib::Object#notify] signal on this property to
/// detect when a handshake has occurred.)
///
/// Readable
///
///
/// #### `peer-certificate-errors`
/// The errors noticed while verifying
/// [`peer-certificate`][struct@crate::TlsConnection#peer-certificate]. Normally this should be 0, but
/// it may not be if [`validation-flags`][struct@crate::TlsClientConnection#validation-flags] is not
/// [`TlsCertificateFlags::VALIDATE_ALL`][crate::TlsCertificateFlags::VALIDATE_ALL], or if
/// [`accept-certificate`][struct@crate::TlsConnection#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 TLS protocol version in use. See [`TlsConnectionExt::protocol_version()`][crate::prelude::TlsConnectionExt::protocol_version()].
///
/// Readable

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

/// ## 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 [`TlsCertificateExt::issuer()`][crate::prelude::TlsCertificateExt::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
/// [`validation_flags`][struct@crate::TlsClientConnection#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
/// [`authentication_mode`][struct@crate::TlsServerConnection#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
/// the user before returning from the signal handler. If you want to
/// let the user decide whether or not to accept the certificate, you
/// would have to return [`false`] from the signal handler on the first
/// attempt, and then after the connection attempt returns a
/// [`TlsError::BadCertificate`][crate::TlsError::BadCertificate], you can interact with the user, and
/// if the user decides to accept the certificate, remember that fact,
/// create a new connection, and return [`true`] from the signal handler
/// the next time.
///
/// If you are doing I/O in another thread, you do not
/// need to worry about this, and can simply block in the signal
/// handler until the UI thread returns an answer.
