Enum ExpInputErrors 

pub enum ExpInputErrors<RawScalar: RawScalarTrait> {
    InvalidExponent {
        source: <RawScalar as RawScalarTrait>::ValidationErrors,
    },
}

Errors that can occur during the input validation phase when attempting to compute the exponential of a number.

This enum is used as a source for the Input variant of ExpErrors. It is generic over RawScalar: RawScalarTrait, where RawScalar is the type of the number for which the exponential is being computed. The source field in the InvalidExponent variant will be of type <RawScalar as RawScalarTrait>::ValidationErrors.

Variants

InvalidExponent

The input exponent failed validation according to the active policy.

This error typically occurs if the input value for the exponential computation (the exponent) failed initial validation checks. For example, using StrictFinitePolicy, this would trigger if the exponent is NaN, Infinity, or (for f64) subnormal.

Fields

source: <RawScalar as RawScalarTrait>::ValidationErrors

The underlying validation error from the input type.

This provides more specific details about why the input exponent was considered invalid by the validation policy. The type of this field is <RawScalar as RawScalarTrait>::ValidationErrors.

Provides type-based access to context intended for error reports.

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
