Enum ArgInputErrors 

pub enum ArgInputErrors<RawComplex: RawComplexTrait> {
    ValidationError {
        source: <RawComplex as RawScalarTrait>::ValidationErrors,
    },
    Zero {
        backtrace: Backtrace,
    },
}

Errors that can occur specifically during the input validation phase or due to special input values when attempting to compute the argument (principal value) of a complex number.

This enum is used as a source for the ArgErrors::Input variant and helps categorize why an input was deemed unsuitable before or during the core argument calculation.

Generic Parameters

• RawComplex: A type that implements RawComplexTrait. This defines the raw error type for the input complex number via <RawComplex as RawScalarTrait>::ValidationErrors.

Variants

ValidationError

The input complex number failed basic validation checks.

This error occurs if the input complex number itself is considered invalid according to the validation policy (e.g., StrictFinitePolicy), such as containing NaN or Infinity components, before the argument calculation is attempted.

Fields

source: <RawComplex as RawScalarTrait>::ValidationErrors

The underlying validation error from the complex number type.

This provides more specific details about why the complex number’s components (real or imaginary parts) were considered invalid.

Zero

The input complex number is zero.

The argument of zero is undefined. This error indicates that the input value was 0 + 0i.

Fields

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
