Enum ATanComplexInputErrors 

pub enum ATanComplexInputErrors<RawComplex: RawComplexTrait> {
    ArgumentIsPole {
        value: RawComplex,
        backtrace: Backtrace,
    },
    InvalidArgument {
        source: <RawComplex as RawScalarTrait>::ValidationErrors,
    },
}

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

This enum is used as a source for the Input variant of ATanComplexErrors. It is generic over RawComplex, which must implement RawComplexTrait. This enum addresses failures in the initial validation of the input complex number (e.g., components being NaN, Infinity, or subnormal) or if the argument is a pole for the complex arctangent function (e.g., 0 +/- 1i).

Variants

ArgumentIsPole

The input complex number is a pole for the arctangent function (e.g., i or -i).

The complex arctangent function is undefined at these points.

Fields

value: RawComplex

The argument value that is a pole.

backtrace: Backtrace

The backtrace of the error.

InvalidArgument

The argument of the function is invalid due to failing general validation checks.

This variant indicates that the argument of the function is invalid w.r.t. the chosen validation policy (e.g. NaN, Infinity). It includes the source error that occurred during validation.

Fields

source: <RawComplex as RawScalarTrait>::ValidationErrors

The source error that occurred during validation.

👎Deprecated since 1.42.0:

use the Display impl or to_string()
