Enum SqrtRealInputErrors 

pub enum SqrtRealInputErrors<RawReal: RawRealTrait> {
    NegativeValue {
        value: RawReal,
        backtrace: Backtrace,
    },
    ValidationError {
        source: <RawReal as RawScalarTrait>::ValidationErrors,
    },
}

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

This enum is used as the source for the Input variant of SqrtRealErrors. It is generic over RawReal: RawRealTrait, which defines the specific raw real number type and its associated validation error type.

Variants

• Self::NegativeValue: The input value is negative, which is not allowed for real square roots.
• Self::ValidationError: The input value failed basic validation checks (e.g., NaN, infinity, subnormal) according to the validation policy.

Variants

NegativeValue

The input value for the square root computation is negative.

The square root of a negative real number is not a real number.

Fields

value: RawReal

The negative input value.

backtrace: Backtrace

The backtrace of the error.

ValidationError

The input value failed basic validation checks (e.g., it is NaN, infinite, or subnormal).

This error occurs if the input value itself is considered invalid according to the validation policy (e.g., StrictFinitePolicy), before the domain-specific check (like negativity) for the square root operation is performed.

Fields

source: <RawReal as RawScalarTrait>::ValidationErrors

The source error that occurred during validation.

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
