Struct quinn::Connecting [−][src]
In-progress connection attempt future
Be sure to spawn the ConnectionDriver when complete.
Implementations
impl Connecting[src]
pub fn into_0rtt(self) -> Result<(NewConnection, ZeroRttAccepted), Self>[src]
Convert into a 0-RTT or 0.5-RTT connection at the cost of weakened security. Be sure to
spawn the ConnectionDriver.
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.
impl Connecting[src]
pub fn remote_address(&self) -> SocketAddr[src]
The peer’s UDP address.
Will panic if called after poll has returned Ready.
