Expression evaluation errors.

Variants

DivisionByZero

Division by zero.

Overflow

Integer overflow.

TypeMismatch

Type mismatch during evaluation.

Fields

expected: String

actual: String

InvalidColumnRef

Invalid column reference (index out of bounds).

Fields

index: usize

UnsupportedExpression(String)

Unsupported expression type.

UnsupportedFunction(String)

Unsupported function call.

Vector(VectorError)

Vector evaluation error.

Trait Implementations

impl Clone for EvaluationError

fn clone(&self) -> EvaluationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvaluationError

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

Formats the value using the given formatter.

impl Display for EvaluationError

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

Formats the value using the given formatter.

impl Error for EvaluationError

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<EvaluationError> for ExecutorError

fn from(source: EvaluationError) -> Self

Converts to this type from the input type.

impl From<VectorError> for EvaluationError

fn from(source: VectorError) -> Self

Converts to this type from the input type.

impl PartialEq for EvaluationError

fn eq(&self, other: &EvaluationError) -> 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.
