ant-quic lifecycle-aware connection close reasons.

Variants

Superseded

A newer connection superseded this one.

ReaderExit

The reader task exited and the endpoint actively closed the connection.

PeerShutdown

The remote endpoint is shutting down.

Banned

Trust or policy enforcement rejected the peer.

LifecycleCleanup

Generic lifecycle cleanup.

LivenessTimeout

X0X-0062: the local endpoint detected the application data path is dead (repeated send_with_receive_ack retries failed within a short window) while the underlying QUIC connection still reports as Live. Used to force-close half-dead connections so callers can re-dial.

ApplicationClosed

The peer sent a non-lifecycle application close.

ConnectionClosed

The peer or transport closed the connection without an application code.

TimedOut

The connection timed out.

Reset

The peer reset the connection.

TransportError

A transport error closed the connection.

LocallyClosed

The local side closed the connection.

VersionMismatch

Version or capability mismatch closed the connection.

CidsExhausted

CID exhaustion closed the connection.

Unknown

Unknown or unmapped close reason.

Implementations

impl ConnectionCloseReason

pub fn app_error_code(self) -> Option<VarInt>

Return the reserved QUIC application error code, if this reason has one.

pub fn as_str(self) -> &'static str

Human-readable identifier for logs and diagnostics.

pub fn reason_bytes(self) -> &'static [u8]

Static reason bytes used in CONNECTION_CLOSE frames.

pub fn from_app_error_code(code: VarInt) -> Option<Self>

Map a QUIC application close code into a lifecycle reason.

pub fn from_connection_error(error: &ConnectionError) -> Self

Map a transport connection error into a lifecycle reason.
