Enum StraddleError 

#[non_exhaustive]
pub enum StraddleError {
    NotAnOption,
    MixedStrategy,
}

Why two options cannot be booked as one strategy.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotAnOption

A leg that is neither an FX option nor a European swaption.

MixedStrategy

Two legs that do not read the same market — two pairs, two currencies, or a swaption and an FX option.

impl Eq for StraddleError

impl Error for StraddleError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for StraddleError

fn eq(&self, other: &StraddleError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
