Struct QuicPinger 

pub struct QuicPinger {
    pub endpoint: String,
    pub timeout: Duration,
    pub alpn: Vec<Vec<u8>>,
    /* private fields */
}

QUIC pinger. Reports the time taken to complete the QUIC handshake (UDP + Initial / Handshake / 1-RTT keys ready). Doesn’t open streams or speak HTTP/3 frames — handshake completion IS the success signal.

Fields

endpoint: String

timeout: Duration

alpn: Vec<Vec<u8>>

Implementations

impl QuicPinger

pub fn new(endpoint: impl Into<String>) -> Self

pub fn with_timeout(self, t: Duration) -> Self

pub fn with_alpn(self, alpn: Vec<Vec<u8>>) -> Self

Replace the ALPN list. Default is [b"h3".to_vec()]. Pass an empty vec to send a TLS ClientHello with no ALPN extension at all — most servers will refuse, but a few legacy QUIC stacks expect that.

pub fn with_tls_config(self, config: Arc<ClientConfig>) -> Self

Inject a custom rustls ClientConfig. The pinger will set the ALPN list on a clone before handing it to quinn, so caller- provided ALPN is overwritten by self.alpn. Use this for self-signed test endpoints (set the trust anchor here).
