Error that occurred during request 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.

BadQuery(BadQuery)

Caller passed an invalid statement.

EmptyPlan

Load balancing policy returned an empty plan.

PrepareError(PrepareError)

Failed to prepare the statement. Applies to unprepared statements with non-empty value parameters.

ConnectionPoolError(ConnectionPoolError)

Selected node’s connection pool is in invalid state.

LastAttemptError(RequestAttemptError)

An error returned by last attempt of request execution.

RequestTimeout(Duration)

Failed to run a request within a provided client timeout.

UseKeyspaceError(UseKeyspaceError)

‘USE KEYSPACE <>’ request failed.

SchemaAgreementError(SchemaAgreementError)

Failed to await automatic schema agreement.

MetadataError(MetadataError)

A metadata error occurred during schema agreement.

Trait Implementations

impl Clone for ExecutionError

fn clone(&self) -> ExecutionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionError

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

Formats the value using the given formatter.

impl Display for ExecutionError

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

Formats the value using the given formatter.

impl Error for ExecutionError

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>)
