Enum scylla::transport::errors::CqlEventHandlingError

#[non_exhaustive]
pub enum CqlEventHandlingError {
    CqlEventParseError(CqlEventParseError),
    UnexpectedResponse(CqlResponseKind),
    BodyExtensionParseError(FrameBodyExtensionsParseError),
    SendError,
}

Failed to handle a CQL event received on a stream -1. Possible error kinds are:

• failed to deserialize response’s frame header
• failed to deserialize CQL event response
• received invalid server response
• failed to send an event info via channel (connection is probably broken)

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.

CqlEventParseError(CqlEventParseError)

Received an EVENT server response, but failed to deserialize it.

UnexpectedResponse(CqlResponseKind)

Received an unexpected response on stream -1.

BodyExtensionParseError(FrameBodyExtensionsParseError)

Failed to deserialize body extensions of frame received on stream -1.

SendError

Driver failed to send event data between the internal tasks. It implies that connection was broken for some reason.

Trait Implementations

impl Debug for CqlEventHandlingError

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

Formats the value using the given formatter.

impl Display for CqlEventHandlingError

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

impl Error for CqlEventHandlingError

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.
