}

Errors returned by the ensemble-method functions.

Variants

Input(InputError)

A malformed indicator matrix passed through to the sequential bootstrap (for example, rows of different lengths).

Empty(&'static str)

The named input is empty.

LengthMismatch(&'static str)

A row of the named input does not have the expected length.

ZeroSampleCount

bootstrap_sample_indices was given n_samples == 0 or sample_size == 0.

Invalid

A scalar argument is outside its domain.

Fields

name: &'static str

Name of the offending argument.

requirement: &'static str

The condition it must satisfy.

NoLabelColumns

The indicator matrix’s first row has no label columns.

EmptyPredictionRows

The model rows have no observations.

NonBinaryLabels

A classification vote received a label other than 0 or 1.

TooFewModels

A pairwise statistic needs at least two model rows.

TooFewPredictionSamples

A correlation needs at least two observations per model row.

Trait Implementations

impl Clone for EnsembleError

fn clone(&self) -> EnsembleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnsembleError

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

Formats the value using the given formatter.

impl Display for EnsembleError

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

Formats the value using the given formatter.

impl Error for EnsembleError

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<InputError> for EnsembleError

fn from(source: InputError) -> Self

Converts to this type from the input type.

impl PartialEq for EnsembleError

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