Errors related to position validation

This enum represents errors that can occur during position validation checks. These errors typically happen when attempting to create or modify a position with invalid or incompatible parameters.

Variants

• InvalidSize - The position size is invalid (e.g., zero, negative, or too large).

• InvalidPrice - The position price is invalid (e.g., negative or unrealistic).

• IncompatibleSide - The position side (long/short) is incompatible with the strategy.

• IncompatibleStyle - The option style is incompatible with the strategy.

• InvalidPosition - The position is invalid for other specific reasons.

Usage

Used when validating positions to ensure they meet all requirements before being added to a strategy or executed in a trading system.

Variants

InvalidSize

Position size is invalid

Occurs when the specified position size violates size constraints.

Fields

size: f64

The invalid size value

reason: String

Explanation of why the size is invalid

InvalidPrice

Position price is invalid

Occurs when the specified price violates price constraints or is unrealistic.

Fields

price: f64

The invalid price value

reason: String

Explanation of why the price is invalid

IncompatibleSide

Position type is incompatible with strategy

Occurs when the position side (long/short) conflicts with strategy requirements.

Fields

position_side: Side

The incompatible position side

reason: String

Explanation of why the side is incompatible

IncompatibleStyle

Option style is incompatible with strategy

Occurs when the option style (American/European) conflicts with strategy requirements.

Fields

style: OptionStyle

The incompatible option style

reason: String

Explanation of why the style is incompatible

InvalidPosition

Position is invalid for other reasons

A general error for positions that fail validation for reasons not covered by other variants.

Fields

reason: String

Explanation of why the position is invalid

Trait Implementations

impl Debug for PositionValidationErrorKind

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

impl Error for PositionValidationErrorKind

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
