Enum ConnectionError 

pub enum ConnectionError {
    VersionMismatch,
    TransportError(Error),
    ConnectionClosed(ConnectionClose),
    ApplicationClosed(ApplicationClose),
    Reset,
    TimedOut,
    LocallyClosed,
    CidsExhausted,
}

Reasons why a connection might be lost

Variants

VersionMismatch

The peer doesn’t implement any supported version

TransportError(Error)

The peer violated the QUIC specification as understood by this implementation

ConnectionClosed(ConnectionClose)

The peer’s QUIC stack aborted the connection automatically

ApplicationClosed(ApplicationClose)

The peer closed the connection

Reset

The peer is unable to continue processing this connection, usually due to having restarted

TimedOut

Communication with the peer has lapsed for longer than the negotiated idle timeout

If neither side is sending keep-alives, a connection will time out after a long enough idle period even if the peer is still reachable. See also TransportConfig::max_idle_timeout() and TransportConfig::keep_alive_interval().

LocallyClosed

The local application closed the connection

CidsExhausted

The connection could not be created because not enough of the CID space is available

Try using longer connection IDs.

Trait Implementations

impl Clone for ConnectionError

fn clone(&self) -> ConnectionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionError

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

Formats the value using the given formatter.

impl Display for ConnectionError

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

Formats the value using the given formatter.

impl Error for ConnectionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Close> for ConnectionError

fn from(x: Close) -> ConnectionError

Converts to this type from the input type.

fn from(error: ConnectionError) -> Self

Converts to this type from the input type.

impl From<ConnectionError> for ReadError

fn from(source: ConnectionError) -> ReadError

Converts to this type from the input type.

impl From<ConnectionError> for ResetError

fn from(source: ConnectionError) -> ResetError

impl PartialEq for ConnectionError

fn eq(&self, other: &ConnectionError) -> 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.
