ColumnLengthMismatch

Fields

col: usize

expected: usize

found: usize

Overflow

Fields

value: String

target: &'static str

LossyCast

Fields

value: String

target: &'static str

TypeError

Fields

from: &'static str

message: Option<String>

NullError

Fields

message: Option<String>

IncompatibleTypeError

Fields

from: &'static str

to: &'static str

message: Option<String>

KernelError(Option<String>)

ShapeError

Fields

message: String

NotImplemented

Fields

feature: String

IndexError(String)

BridgeError

External bridge failure surfaced by to_apache_arrow / to_polars / from_apache_arrow / from_polars or any of their try_* siblings. source identifies the foreign library (e.g. "arrow-rs", "polars") so the same variant can carry errors from either bridge.

Fields

source: &'static str

message: String

DictionaryOverflow

Raised when a categorical operation would exceed the index type’s cardinality, e.g. a 257th unique value on a u8 categorical.

Trait Implementations

impl Debug for MinarrowError

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

Formats the value using the given formatter.

impl Display for MinarrowError

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

Formats the value using the given formatter.

impl Error for MinarrowError

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 MinarrowError

Available on crate feature cast_arrow only.

fn from(e: ArrowError) -> Self

Converts to this type from the input type.

impl From<DictionaryError> for MinarrowError

Available on crate feature shared_dict only.

fn from(source: DictionaryError) -> Self

Converts to this type from the input type.

impl From<KernelError> for MinarrowError

fn from(err: KernelError) -> Self

Converts to this type from the input type.

impl From<PolarsError> for MinarrowError

Available on crate feature cast_polars only.

fn from(e: PolarsError) -> Self

Converts to this type from the input type.

impl PartialEq for MinarrowError

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