Variants

InvalidBounds

Returned when the lower bound is greater than the upper bound.

Fields

low: f64

The lower bound value.

high: f64

The upper bound value.

InvalidLogBounds

Returned when log scale is used with non-positive bounds.

InvalidStep

Returned when step size is not positive.

EmptyChoices

Returned when categorical choices are empty.

ParameterConflict

Returned when a parameter is suggested with a different configuration.

Fields

name: String

The name of the conflicting parameter.

reason: String

The reason for the conflict.

NoCompletedTrials

Returned when requesting the best trial but no trials have completed.

InvalidGamma(f64)

Returned when gamma is not in the valid range (0.0, 1.0).

InvalidBandwidth(f64)

Returned when bandwidth is not positive.

EmptySamples

Returned when KDE is created with empty samples.

Internal(&'static str)

Returned when an internal invariant is violated.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
