Errors returned by clustering and mixture-model fitting.

Variants

EmptyInput

No observations were supplied.

ZeroDimension

An observation had no coordinates.

DimensionMismatch

Observation dimensions were inconsistent.

Fields

expected: usize

Expected coordinate count.

actual: usize

Actual coordinate count.

point: usize

Index of the mismatching observation.

NonFiniteInput

An observation contained NaN or infinity.

Fields

point: usize

Observation index.

coordinate: usize

Coordinate index.

value: f64

Rejected value.

InvalidComponentCount

A requested component count cannot be fitted to the observations.

Fields

components: usize

Requested component count.

points: usize

Number of supplied observations.

InvalidControl

A control or model field was invalid.

Fields

field: &'static str

Name of the invalid field.

reason: &'static str

Stable reason for rejection.

WorkLimit

The work bound could not admit one complete initial model.

Fields

limit: u64

Configured work bound.

used: u64

Work already charged when admission failed.

ArithmeticOverflow

Size or work accounting overflowed.

Fields

operation: &'static str

Operation whose accounting overflowed.

SingularComponent

A component could not be made numerically nonsingular under policy.

Fields

component: usize

Component index in stable model order.

NumericalFailure

Finite inputs produced a non-finite intermediate result.

Fields

operation: &'static str

Operation that failed.

Trait Implementations

impl Clone for ClusteringError

fn clone(&self) -> ClusteringError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClusteringError

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

Formats the value using the given formatter.

impl Display for ClusteringError

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

Formats the value using the given formatter.

impl Error for ClusteringError

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 PartialEq for ClusteringError

fn eq(&self, other: &ClusteringError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
