Enum BadQuery

#[non_exhaustive]
pub enum BadQuery {
    PartitionKeyExtraction,
    SerializationError(SerializationError),
    ValuesTooLongForKey(usize, usize),
    TooManyQueriesInBatchStatement(usize),
}

Error caused by caller creating an invalid statement.

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.

PartitionKeyExtraction

Unable extract a partition key based on prepared statement’s metadata.

SerializationError(SerializationError)

“Serializing values failed.

ValuesTooLongForKey(usize, usize)

Serialized values are too long to compute partition key.

TooManyQueriesInBatchStatement(usize)

Too many statements in the batch statement.

Trait Implementations

impl Clone for BadQuery

fn clone(&self) -> BadQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BadQuery

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

Formats the value using the given formatter.

impl Display for BadQuery

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

Formats the value using the given formatter.

impl Error for BadQuery

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<BadQuery> for ExecutionError

fn from(source: BadQuery) -> Self

Converts to this type from the input type.

impl From<SerializationError> for BadQuery

fn from(source: SerializationError) -> Self

Converts to this type from the input type.
