Enum PowIntExponentInputErrors

pub enum PowIntExponentInputErrors<RawScalar: RawScalarTrait, ExponentType: IntegerExponent> {
    InvalidBase {
        source: <RawScalar as RawScalarTrait>::ValidationErrors,
    },
    ZeroBaseNegativeExponent {
        exponent: ExponentType,
        backtrace: Backtrace,
    },
}

Errors that can occur during input validation when computing base^exponent where the exponent is an integer type.

This enum is typically used as the InputErrorSource for PowIntExponentErrors. It is generic over RawScalar, which must implement RawScalarTrait, and IntExponentType, which is the integer type of the exponent.

Variants

InvalidBase

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

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

Fields

source: <RawScalar as RawScalarTrait>::ValidationErrors

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

ZeroBaseNegativeExponent

The base is zero, and the integer exponent is negative. This operation results in division by zero.

Fields

exponent: ExponentType

The negative integer exponent value.

backtrace: Backtrace

A captured backtrace for debugging purposes.

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
