Struct ConnectionStats 

#[non_exhaustive]
pub struct ConnectionStats {
    pub rtt: Option<Duration>,
    pub estimated_send_rate: Option<u64>,
    pub estimated_recv_rate: Option<u64>,
    pub bytes_sent: Option<u64>,
    pub bytes_received: Option<u64>,
    pub bytes_lost: Option<u64>,
    pub packets_sent: Option<u64>,
    pub packets_received: Option<u64>,
    pub packets_lost: Option<u64>,
}

A snapshot of connection statistics for a Session.

Every field is optional: availability depends on the transport backend (native QUIC reports all of them, the browser WebTransport reports few or none) and on the connection state (e.g. estimated_send_rate is None until the congestion controller has a window). None means “not reported”, not “zero”.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rtt: Option<Duration>

Smoothed round-trip time estimate.

estimated_send_rate: Option<u64>

Estimated send bandwidth from the congestion controller, in bits per second.

estimated_recv_rate: Option<u64>

Estimated receive bandwidth from MoQ PROBE, in bits per second.

None unless the negotiated version supports PROBE (moq-lite-03+).

bytes_sent: Option<u64>

Total bytes sent over the connection, including retransmissions and overhead.

bytes_received: Option<u64>

Total bytes received over the connection, including duplicates and overhead.

bytes_lost: Option<u64>

Total bytes lost (detected via retransmission or acknowledgement).

packets_sent: Option<u64>

Total datagrams sent.

packets_received: Option<u64>

Total datagrams received.

packets_lost: Option<u64>

Total datagrams detected as lost.
