Enum PowRealBaseRealExponentInputErrors 

pub enum PowRealBaseRealExponentInputErrors<RawReal: RawRealTrait> {
    NegativeBase {
        base: RawReal,
        exponent: RawReal,
        backtrace: Backtrace,
    },
    InvalidBase {
        source: <RawReal as RawScalarTrait>::ValidationErrors,

        error_exponent: <RawReal as RawScalarTrait>::ValidationErrors,
        backtrace: Backtrace,
    },
}

Errors that can occur during input validation when computing base^exponent where both the base and exponent are real numbers.

This enum is typically used as the InputErrorSource for a FunctionErrors wrapper, such as PowRealBaseRealExponentErrors. It is generic over RawReal, which must implement RawRealTrait.

Variants

NegativeBase

The base is negative, and the exponent is a non-integer real number. This operation is undefined in the real domain and typically results in a complex number or NaN.

Fields

base: RawReal

The negative base value.

exponent: RawReal

The exponent value.

backtrace: Backtrace

A captured backtrace for debugging purposes.

InvalidBase

The input base value failed validation according to the active policy.

For example, using StrictFinitePolicy, this would trigger if the base is NaN or Infinity.

Fields

source: <RawReal as RawScalarTrait>::ValidationErrors

The underlying validation error for the base. The type of this field is <RawReal as RawScalarTrait>::ValidationErrors.

InvalidExponent

The input exponent value failed validation according to the active policy.

For example, using StrictFinitePolicy, this would trigger if the exponent is NaN or Infinity.

Fields

source: <RawReal as RawScalarTrait>::ValidationErrors

The underlying validation error for the exponent. The type of this field is <RawReal as RawScalarTrait>::ValidationErrors.

InvalidBaseAndExponent

Both the base and the exponent are invalid according to the validation policy.

This error occurs when both input values fail validation checks simultaneously.

Fields

error_base: <RawReal as RawScalarTrait>::ValidationErrors

The source error that occurred during validation for the base.

error_exponent: <RawReal as RawScalarTrait>::ValidationErrors

The source error that occurred during validation for the exponent.

backtrace: Backtrace

A captured backtrace for debugging purposes.
