SQL-layer errors.

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.

EmptyQuery

Query was empty or whitespace only.

EmptyTableName

A table name was empty.

Unsupported

The requested SQL feature is not available in R1.

Fields

feature: String

InvalidTableFunction

A table-function declaration or runtime registration was invalid.

Fields

message: String

DataFusion

DataFusion returned an error.

Fields

message: String

Optimizer(OptimizerError)

Krishiv logical-plan optimization failed.

AccessDenied

Access denied by auth or policy check.

Fields

reason: String

OperationCancelled

A running operation was cancelled by the caller.

Fields

operation_id: u64

Timeout

A query exceeded its configured execution timeout.

Fields

timeout_ms: u64

Trait Implementations

impl Clone for SqlError

fn clone(&self) -> SqlError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlError

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

Formats the value using the given formatter.

impl Display for SqlError

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

Formats the value using the given formatter.

impl Eq for SqlError

impl Error for SqlError

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<DataFusionError> for SqlError

fn from(value: DataFusionError) -> Self

Converts to this type from the input type.

impl From<OptimizerError> for SqlError

fn from(source: OptimizerError) -> Self

Converts to this type from the input type.

impl PartialEq for SqlError

fn eq(&self, other: &SqlError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
