Represents different types of input validation errors that can occur during financial calculations.

This enum encapsulates various error conditions related to the validation of input parameters in financial models, particularly for options pricing and risk analysis. Each variant contains detailed information about the invalid input, including both the problematic value and a reason explaining why it was rejected.

Variants

• InvalidVolatility - Represents errors related to improper volatility values such as negative values or unreasonably large inputs that would cause calculation issues.

• InvalidTime - Represents errors related to time inputs (typically time to expiration) that are outside acceptable bounds or otherwise unsuitable for financial calculations.

• InvalidPrice - Represents errors related to price inputs (like underlying asset prices) that are negative or otherwise invalid for the calculation context.

• InvalidRate - Represents errors related to interest rate values that are outside acceptable bounds for the specific financial modeling context.

• InvalidStrike - Represents errors related to strike price inputs that are malformed, out of bounds, or otherwise unsuitable for options calculations.

Usage

These error kinds are typically used within higher-level error types to provide specific information about validation failures, enabling precise error handling and informative error messages for users.

Variants

InvalidVolatility

Error indicating an invalid volatility input.

This error occurs when a volatility value is outside acceptable bounds (typically negative values or unreasonably large values) or otherwise invalid for the calculation being performed.

Fields

value: f64

The invalid volatility value that was provided

reason: String

Detailed explanation of why the volatility value is invalid

InvalidTime

Error indicating an invalid time input.

This error occurs when a time value (typically representing time to expiration) is outside acceptable bounds or otherwise invalid for the calculation being performed.

Fields

value: Positive

The invalid time value that was provided (as a Positive type)

reason: String

Detailed explanation of why the time value is invalid

InvalidPrice

Error indicating an invalid price input.

This error occurs when a price value (such as an underlying asset price) is outside acceptable bounds (typically negative values) or otherwise invalid for the calculation being performed.

Fields

value: f64

The invalid price value that was provided

reason: String

Detailed explanation of why the price value is invalid

InvalidRate

Error indicating an invalid interest rate input.

This error occurs when an interest rate value is outside acceptable bounds or otherwise invalid for the calculation being performed.

Fields

value: f64

The invalid interest rate value that was provided

reason: String

Detailed explanation of why the rate value is invalid

InvalidStrike

Error indicating an invalid strike price input.

This error occurs when a strike price value is outside acceptable bounds, in an incorrect format, or otherwise invalid for the calculation being performed.

Fields

value: String

The invalid strike value that was provided (as a String)

reason: String

Detailed explanation of why the strike value is invalid

Trait Implementations

impl Debug for InputErrorKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for InputErrorKind

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for InputErrorKind

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)
