Errors that can occur when executing a scalar function

Variants

ArityMismatch

Function called with wrong number of arguments

Fields

function: Fragment

expected: usize

actual: usize

InvalidArgumentType

Argument has invalid type

Fields

function: Fragment

argument_index: usize

expected: Vec<Type>

actual: Type

ExecutionFailed

Function execution failed

Fields

function: Fragment

reason: String

Wrapped(Box<Error>)

Wrapped error from underlying operation

Trait Implementations

impl Debug for ScalarFunctionError

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

Formats the value using the given formatter.

impl Display for ScalarFunctionError

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

Formats the value using the given formatter.

impl Error for ScalarFunctionError

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<Error> for ScalarFunctionError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ScalarFunctionError> for Error

fn from(err: ScalarFunctionError) -> Self

Converts to this type from the input type.
