Struct ConnectionDiagnostics 

#[non_exhaustive]
pub struct ConnectionDiagnostics {
    pub server: String,

Per-connection snapshot, captured by Connection::diagnostics and included in Diagnostics::primary / Diagnostics::extra_connections.

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.

server: String

Server hostname or IP this connection talks to.

negotiated: Option<NegotiatedSummary>

Negotiated parameters, or None until negotiate() runs.

credits: CreditInfo

Credit gauge + in-flight count + next-MessageId.

signing: SigningInfo

Signing state.

encryption: EncryptionInfo

Encryption state.

compression: CompressionInfo

Compression state.

rtt_estimate: Option<Duration>

RTT measured during negotiate, if it ran.

disconnected: bool

true after the receiver task has torn down (transport error, decrypt failure, etc.).

dfs_trees: Vec<TreeId>

Tree IDs that have DFS capability on this connection.

session: Option<SessionDiagnostics>

Session on this connection, or None until session setup runs.

metrics: MetricsSnapshot

Per-connection counters.

outstanding: Vec<OutstandingRequest>

Requests sent and not yet answered, oldest first.

Empty on a healthy idle connection. A long-lived entry here is the signature of a hung request; see OutstandingRequest.
