Struct ConnectionOutputs 

pub struct ConnectionOutputs { /* private fields */ }

Facts about the connection learned through the handshake.

Implementations

impl ConnectionOutputs

pub fn peer_identity(&self) -> Option<&Identity<'static>>

Retrieves the certificate chain or the raw public key used by the peer to authenticate.

This is made available for both full and resumed handshakes.

For clients, this is the identity of the server. For servers, this is the identity of the client, if client authentication was completed.

The return value is None until this value is available.

pub fn alpn_protocol(&self) -> Option<&ApplicationProtocol<'static>>

Retrieves the protocol agreed with the peer via ALPN.

A return value of None after handshake completion means no protocol was agreed (because no protocols were offered or accepted by the peer).

pub fn negotiated_cipher_suite(&self) -> Option<SupportedCipherSuite>

Retrieves the cipher suite agreed with the peer.

This returns None until the cipher suite is agreed.

pub fn negotiated_key_exchange_group( &self, ) -> Option<&'static dyn SupportedKxGroup>

Retrieves the key exchange group agreed with the peer.

This function may return None depending on the state of the connection, the type of handshake, and the protocol version.

If CommonState::is_handshaking() is true this function will return None. Similarly, if the ConnectionOutputs::handshake_kind() is HandshakeKind::Resumed and the ConnectionOutputs::protocol_version() is TLS 1.2, then no key exchange will have occurred and this function will return None.

pub fn protocol_version(&self) -> Option<ProtocolVersion>

Retrieves the protocol version agreed with the peer.

This returns None until the version is agreed.

pub fn handshake_kind(&self) -> Option<HandshakeKind>

Which kind of handshake was performed.

This tells you whether the handshake was a resumption or not.

This will return None before it is known which sort of handshake occurred.

pub fn tls13_tickets_received(&self) -> u32

Returns the number of TLS1.3 tickets that have been received.

Only clients receive tickets, so this is zero for servers.

pub fn fips(&self) -> FipsStatus

Return the FIPS validation status of the connection.

This is different from crate::crypto::CryptoProvider::fips(): it is concerned only with cryptography, whereas this also covers TLS-level configuration that NIST recommends, as well as ECH HPKE suites if applicable.

Trait Implementations

impl Default for ConnectionOutputs

fn default() -> Self

Returns the “default value” for a type.
