    InvalidDomain,
    NonPositiveVariance {
        k: f64,
        w: f64,
    },
    IllConditionedVariance {

    NonFiniteEvaluation {
        k: f64,
    },
}

Error returned when density evaluation or integration has no finite domain.

Variants

InvalidDomain

The requested range, panel count, or point is invalid.

NonPositiveVariance

Total variance is non-positive at the requested log-moneyness.

Fields

k: f64

Log-moneyness of the singularity.

w: f64

Evaluated total variance.

IllConditionedVariance

Positive variance is too close to floating-point cancellation for a reliable regular-density evaluation.

Fields

k: f64

Log-moneyness of the ill-conditioned evaluation.

w: f64

Positive total variance obtained in binary64.

uncertainty: f64

Scale-aware uncertainty threshold used for classification.

NonFiniteEvaluation

Floating-point evaluation overflowed or produced NaN.

Fields

k: f64

Log-moneyness of the failed evaluation.

Trait Implementations
