Errors from Arrow-backed sequences.

Variants

Core(Error)

An error from the core crate, such as invalid runs or unequal lengths.

Arrow(ArrowError)

An error from an Arrow kernel, such as mismatched types or overflow.

InvalidFill

A fill value was not a single value of the right type.

Fields

expected: DataType

actual: DataType

len: usize

WrongLength

An operation returned a different number of values than it was given.

Fields

expected: usize

actual: usize

KeySchemaMismatch

Two batches have keys with different column names or types.

UnsupportedType(DataType)

The values have a type this operation does not support.

UnexpectedNulls

The values contain nulls where they are not allowed.

MissingValues

An aggregation needs values but none were given.

NoInputs

An operation needs at least one input but was given none.

InKey

An operation failed for the key at position in the output.

Fields

position: usize

source: Box<Error>

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<ArrowError> for Error

fn from(e: ArrowError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
