[−][src]Struct quinn::generic::Connecting
In-progress connection attempt future
Methods
impl<S> Connecting<S> where
S: Session,
[src]
S: Session,
pub fn into_0rtt(self) -> Result<(NewConnection<S>, ZeroRttAccepted), Self>
[src]
Convert into a 0-RTT or 0.5-RTT connection at the cost of weakened security
Opens up the connection for use before the handshake finishes, allowing the API user to send data with 0-RTT encryption if the necessary key material is available. This is useful for reducing start-up latency by beginning transmission of application data without waiting for the handshake's cryptographic security guarantees to be established.
When the ZeroRttAccepted
future completes, the connection has been fully established.
Security
On outgoing connections, this enables transmission of 0-RTT data, which might be vulnerable to replay attacks, and should therefore never invoke non-idempotent operations.
On incoming connections, this enables transmission of 0.5-RTT data, which might be intercepted by a man-in-the-middle. If this occurs, the handshake will not complete successfully.
Errors
Outgoing connections are only 0-RTT-capable when a cryptographic session ticket cached from
a previous connection to the same server is available, and includes a 0-RTT key. If no such
ticket is found, self
is returned unmodified.
For incoming connections, a 0.5-RTT connection will always be successfully constructed.
pub fn authentication_data(&self) -> S::AuthenticationData
[src]
Data conveyed by the peer during the handshake, including cryptographic identity
Since the handshake is incomplete at this point, the returned data is likely to be incomplete as well.
impl<S> Connecting<S> where
S: Session,
[src]
S: Session,
pub fn remote_address(&self) -> SocketAddr
[src]
The peer's UDP address.
Will panic if called after poll
has returned Ready
.
