Enum IndicatorError 

pub enum IndicatorError {
    EmptySet,
    EmptyPoint,
    DimensionMismatch,
    NonFiniteValue,
    ReferencePointViolation,
    InsufficientSamples,
}

Validation failures returned by quality indicators.

Variants

EmptySet

A front or reference set was empty.

EmptyPoint

A point had no objective coordinates.

DimensionMismatch

Point and reference dimensions differed.

NonFiniteValue

An objective coordinate was NaN or infinite.

ReferencePointViolation

A hypervolume point lay outside the reference box.

InsufficientSamples

A sampled estimate requested fewer than two samples.

impl Eq for IndicatorError

impl Error for IndicatorError

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 IndicatorError

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

Equality operator ==.

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

Inequality operator !=.
