Enum Mark 

enum Mark {
    BaseCorrelation(Arc<BaseCorrelation>),
    CmsSpreadCorrelation(CmsSpreadCorrelationCurve),
    Scalar(f64),
    Pair((f64, f64)),
}

One model mark as the store holds it: the payload a MarkId maps to. A mark is a parameter someone chose rather than a curve calibrated from instruments or a fact already printed — a correlation, a floor, a degree of freedom, a watched scalar — and the identity decides its shape: a base correlation is a curve over detachments, a CMS spread correlation a flat mark or a term structure, a copula’s degrees of freedom a pair, the rest one number.

Variants

BaseCorrelation(Arc<BaseCorrelation>)

CmsSpreadCorrelation(CmsSpreadCorrelationCurve)

Scalar(f64)

Pair((f64, f64))

Implementations

impl Mark

fn parameter_count(&self) -> usize

fn extend_into(&self, out: &mut Vec<f64>)

Appends the mark’s parameters to out, in the order its labels name.

fn base_correlation(&self) -> Option<&Arc<BaseCorrelation>>

fn cms_spread_correlation(&self) -> Option<&CmsSpreadCorrelationCurve>

fn scalar(&self) -> Option<&f64>

fn pair(&self) -> Option<&(f64, f64)>

Trait Implementations

impl Clone for Mark

fn clone(&self) -> Mark

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mark

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

Formats the value using the given formatter.

impl PartialEq for Mark

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