Enum ParameterLabel 

#[non_exhaustive]
pub enum ParameterLabel {
    Pillar(NaiveDate),
    Meeting(MeetingId),
    Turn(NaiveDate),
    Level,
    Spot,
}

What one free parameter of a curve is, for risk labelling.

The order a curve reports these in is exactly the order Curve::view_with consumes a substituted vector and Curve::view_seeded counts a flat index — one walk, so a risk row and a seeded direction cannot come to mean different pillars.

This lives on the storage, never on the evaluation trait. A curve’s job is to answer what it is worth; what a risk ladder calls its parameters is the lift’s business.

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.

Pillar(NaiveDate)

An ordinary dated pillar.

Meeting(MeetingId)

A step-curve pillar anchored at a central-bank policy decision.

Turn(NaiveDate)

A step-curve pillar anchored at a turn-of-period jump.

Level

A single undated level — a flat hazard, a quoted level with no pillar.

Spot

An FX spot owned by an implied curve.

Trait Implementations

impl Clone for ParameterLabel

fn clone(&self) -> ParameterLabel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterLabel

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

Formats the value using the given formatter.

impl Eq for ParameterLabel

impl PartialEq for ParameterLabel

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