Variants

UnknownColumn(String)

UnsupportedColumnType

Fields

column: String

type_name: &'static str

EncodingMismatch

Fields

column: String

encoding: &'static str

column_type: &'static str

NullCategorical

Categorical encoding requested but the column row at this index is null. Phase 1 does not have a null policy — this is an error.

Fields

column: String

row: u32

EmptySplit(Split)

InvalidFractions

Fractions must each be in [0, 1] and sum to ≤ 1.

Fields

train: f64

val: f64

test: f64

BadBatchSize(usize)

NoFeatures

OrphanEncoding(String)

Encoding was registered for a column not in feature_cols or label_col.

Tidy(String)

Shape(String)

Trait Implementations

impl Clone for DatasetError

fn clone(&self) -> DatasetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatasetError

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

Formats the value using the given formatter.

impl Display for DatasetError

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

Formats the value using the given formatter.

impl Error for DatasetError

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<TidyError> for DatasetError

fn from(e: TidyError) -> Self

Converts to this type from the input type.

impl PartialEq for DatasetError

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