Enum scylla::transport::errors::BrokenConnectionErrorKind

#[non_exhaustive]
pub enum BrokenConnectionErrorKind {
    KeepaliveTimeout(IpAddr),
    KeepaliveQueryError(RequestError),
    FrameHeaderParseError(FrameHeaderParseError),
    CqlEventHandlingError(CqlEventHandlingError),
    UnexpectedStreamId(i16),
    WriteError(Error),
    TooManyOrphanedStreamIds(u16),
    ChannelError,
}

A reason why connection was broken.

See BrokenConnectionError::downcast_ref(). You can retrieve the actual type by downcasting Arc<dyn Error>.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

KeepaliveTimeout(IpAddr)

Driver sent a keepalive request to the database, but the request timed out.

KeepaliveQueryError(RequestError)

Driver sent a keepalive request to the database, but request execution failed.

FrameHeaderParseError(FrameHeaderParseError)

Failed to deserialize response frame header.

CqlEventHandlingError(CqlEventHandlingError)

Failed to handle a CQL event (server response received on stream -1).

UnexpectedStreamId(i16)

Received a server frame with unexpected stream id.

WriteError(Error)

IO error - server failed to write data to the socket.

TooManyOrphanedStreamIds(u16)

Maximum number of orphaned streams exceeded.

ChannelError

Failed to send data via tokio channel. This implies that connection was probably already broken for some other reason.

Trait Implementations

impl Debug for BrokenConnectionErrorKind

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

Formats the value using the given formatter.

impl Display for BrokenConnectionErrorKind

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

Formats the value using the given formatter.

impl Error for BrokenConnectionErrorKind

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

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<BrokenConnectionErrorKind> for BrokenConnectionError

fn from(value: BrokenConnectionErrorKind) -> Self

Converts to this type from the input type.

impl From<CqlEventHandlingError> for BrokenConnectionErrorKind

fn from(source: CqlEventHandlingError) -> Self

Converts to this type from the input type.
