Number of frames transmitted or received of each frame type

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.

acks: u64

ACK frames (RFC 9000 §19.3).

ack_frequency: u64

ACK_FREQUENCY frames, from the ack-frequency extension.

crypto: u64

CRYPTO frames carrying handshake data (§19.6).

connection_close: u64

CONNECTION_CLOSE frames of either kind (§19.19).

data_blocked: u64

DATA_BLOCKED frames, saying the connection’s data limit was reached (§19.12).

datagram: u64

DATAGRAM frames, from the unreliable-datagram extension (RFC 9221).

handshake_done: u8

HANDSHAKE_DONE frames counted as they pass, retransmissions included (§19.20). Saturates at u8::MAX.

immediate_ack: u64

IMMEDIATE_ACK frames, from the ack-frequency extension.

max_data: u64

MAX_DATA frames, raising the connection’s data limit (§19.9).

max_stream_data: u64

MAX_STREAM_DATA frames, raising one stream’s limit (§19.10).

max_streams_bidi: u64

MAX_STREAMS frames for bidirectional streams (§19.11).

max_streams_uni: u64

MAX_STREAMS frames for unidirectional streams (§19.11).

new_connection_id: u64

NEW_CONNECTION_ID frames offering another identifier (§19.15).

new_token: u64

NEW_TOKEN frames carrying an address-validation token (§19.7).

new_token_failed: u64

NEW_TOKEN frames that were not sent because the token could not be sealed. Never received: it counts a local failure.

path_challenge: u64

PATH_CHALLENGE frames probing a path (§19.17).

path_response: u64

PATH_RESPONSE frames answering a probe (§19.18).

ping: u64

PING frames (§19.2).

reset_stream: u64

RESET_STREAM frames giving up on a stream (§19.4).

retire_connection_id: u64

RETIRE_CONNECTION_ID frames dropping an identifier (§19.16).

stream_data_blocked: u64

STREAM_DATA_BLOCKED frames, saying one stream’s limit was reached (§19.13).

streams_blocked_bidi: u64

STREAMS_BLOCKED frames for bidirectional streams (§19.14).

streams_blocked_uni: u64

STREAMS_BLOCKED frames for unidirectional streams (§19.14).

stop_sending: u64

STOP_SENDING frames asking a peer to stop writing a stream (§19.5).

stream: u64

STREAM frames carrying application data (§19.8).
