Errors that can occur during Arrow <-> ndarray conversions.

Variants

NullsPresent

Arrow array contains null values where none were expected.

Fields

null_count: usize

Number of null values found.

TypeMismatch

The Arrow array’s data type does not match the expected type.

Fields

message: String

Human-readable description of the mismatch.

ShapeMismatch

The array shape is incompatible with the requested ndarray shape.

Fields

message: String

Human-readable description of the mismatch.

InvalidMetadata

Extension type metadata is missing or invalid.

Fields

message: String

Human-readable description of the problem.

InnerTypeMismatch

The inner array of a composite type (FixedSizeList, Struct) is not the expected type.

Fields

message: String

Human-readable description of the mismatch.

NonStandardLayout

The ndarray is not in standard (C-contiguous) layout and cannot be transferred to Arrow without copying.

SparseOffsetMismatch

Sparse arrays have mismatched offsets between indices and values columns.

Arrow(ArrowError)

An error propagated from the arrow crate.

Shape(ShapeError)

An ndarray shape error.

Trait Implementations

impl Debug for NdarrowError

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

Formats the value using the given formatter.

impl Display for NdarrowError

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

Formats the value using the given formatter.

impl Error for NdarrowError

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 NdarrowError

fn from(err: ArrowError) -> Self

Converts to this type from the input type.

impl From<ShapeError> for NdarrowError

fn from(err: ShapeError) -> Self

Converts to this type from the input type.
