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Superseded

A newer connection superseded this one.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.

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.

Trait Implementations

impl Clone for ConnectionCloseReason

fn clone(&self) -> ConnectionCloseReason

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectionCloseReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ConnectionCloseReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ConnectionCloseReason

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConnectionCloseReason

fn eq(&self, other: &ConnectionCloseReason) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
