Error that occurred during query execution

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.

DbError(DbError, String)

Database sent a response containing some error with a message

BadQuery(BadQuery)

Caller passed an invalid query

CqlRequestSerialization(CqlRequestSerializationError)

Failed to serialize CQL request.

BodyExtensionsParseError(FrameBodyExtensionsParseError)

Failed to deserialize frame body extensions.

EmptyPlan

Load balancing policy returned an empty plan.

CqlResultParseError(CqlResultParseError)

Received a RESULT server response, but failed to deserialize it.

CqlErrorParseError(CqlErrorParseError)

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

MetadataError(MetadataError)

A metadata error occurred during schema agreement.

ConnectionPoolError(ConnectionPoolError)

Selected node’s connection pool is in invalid state.

ProtocolError(ProtocolError)

Protocol error.

TimeoutError

Timeout error has occurred, function didn’t complete in time.

BrokenConnection(BrokenConnectionError)

A connection has been broken during query execution.

UnableToAllocStreamId

Driver was unable to allocate a stream id to execute a query on.

RequestTimeout(String)

Client timeout occurred before any response arrived

NextRowError(NextRowError)

An error occurred during async iteration over rows of result.

IntoLegacyQueryResultError(IntoLegacyQueryResultError)

👎Deprecated since 0.15.1: Legacy deserialization API is inefficient and is going to be removed soon

Failed to convert QueryResult into LegacyQueryResult.

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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)
