Statistics related to a transmission path

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: Duration

Current best estimate of this connection’s latency (round-trip-time)

min_rtt: Duration

Minimum RTT seen on this path, ignoring ack delay

cwnd: u64

Current congestion window of the connection

ssthresh: Option<u64>

The window at which the controller leaves slow start, when it has one. BBR paces instead and reports none.

pacing_rate: Option<u64>

The rate the controller paces at, in bits per second, when it paces.

congestion_events: u64

Congestion events on the connection

lost_packets: u64

The amount of packets lost on this path

deferred_migrations: u64

Peer moves deferred because no unused destination connection ID was available

preferred_address_probes: u64

PATH_CHALLENGE probes transmitted towards a server’s preferred address

unanswered_off_path_challenges: u64

PATH_CHALLENGEs from a path this connection has no connection ID for, so their answers were dropped rather than sent with an identifier used elsewhere

lost_bytes: u64

The amount of bytes lost on this path

sent_packets: u64

The amount of packets sent on this path

sent_plpmtud_probes: u64

The amount of PLPMTUD probe packets sent on this path (also counted by sent_packets)

lost_plpmtud_probes: u64

The amount of PLPMTUD probe packets lost on this path (ignored by lost_packets and lost_bytes)

black_holes_detected: u64

The number of times a black hole was detected in the path

current_mtu: u16

Largest UDP payload size the path currently supports
