Enum CreditVolError 

#[non_exhaustive]
pub enum CreditVolError {
    Empty,
    Expiry(f64),
    Vol(f64),
    ParameterCount {
        expected: usize,
        given: usize,
    },
}

A credit vol surface that cannot be built as specified.

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.

Empty

No points.

Expiry(f64)

An expiry not strictly increasing and positive, in years.

Vol(f64)

A vol that is not finite and strictly positive.

ParameterCount

Lifted parameters whose count is not the surface’s point count.

Fields

expected: usize

The surface’s point count.

given: usize

The count given.

Trait Implementations

impl Clone for CreditVolError

fn clone(&self) -> CreditVolError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for CreditVolError

impl Debug for CreditVolError

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

Formats the value using the given formatter.

impl Display for CreditVolError

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

Formats the value using the given formatter.

impl Error for CreditVolError

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 CreditVolError

fn eq(&self, other: &CreditVolError) -> 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.
