Enum RateVolError 

#[non_exhaustive]
pub enum RateVolError {
    Malformed(&'static str),
    WrongStrikeAxis {
        asked: &'static str,
        carried: &'static str,
    },
    ParameterCountMismatch {
        expected: usize,
        given: usize,
    },
    NeedsForward {
        read: &'static str,
    },
    Sabr(SabrError),
}

A surface that cannot be built or cannot answer.

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.

Malformed(&'static str)

An empty or non-ascending axis, a ragged grid, or a non-finite or non-positive vol.

WrongStrikeAxis

A read named a coordinate the surface’s strike axis does not carry.

Fields

asked: &'static str

What the read asked for.

carried: &'static str

What the surface’s axis measures.

ParameterCountMismatch

A substituted view was handed the wrong number of parameters.

Fields

expected: usize

How many the surface has.

given: usize

How many were supplied.

NeedsForward

A SABR smile was asked for a read that names no forward — a model smile is a function of the forward as well as the strike.

Fields

read: &'static str

The read that was asked.

Sabr(SabrError)

The SABR formula or its ATM solve refused the inputs.

Trait Implementations

impl Clone for RateVolError

fn clone(&self) -> RateVolError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RateVolError

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

Formats the value using the given formatter.

impl Display for RateVolError

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

Formats the value using the given formatter.

impl Error for RateVolError

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 From<RateVolError> for MarketDataError

fn from(e: RateVolError) -> Self

Converts to this type from the input type.

impl PartialEq for RateVolError

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