Enum Locator 

#[non_exhaustive]
pub enum Locator {
    Tenor(Period),
    Date(NaiveDate),
    Contract(String),
    Window(WindowEnd, WindowEnd),
}

Where a quote sits on its curve, in the spellings a quote sheet uses: a tenor (4Y), a date (2027-03-18), a contract code (SEP27), or a window of two dates or two codes (2026-10-29 - 2026-12-10, SEP27 - DEC27, also spelled with ..). The sheet binder and the helpers dispatch on its shape.

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.

Tenor(Period)

A tenor from the template’s start.

Date(NaiveDate)

An exact date.

Contract(String)

A futures contract code or YYYY-MM month.

Window(WindowEnd, WindowEnd)

A window from one end to the other.

Implementations

impl Locator

pub fn parse(spelling: &str) -> Result<Self, RungBuildError>

Parses a sheet spelling.

Errors

RungBuildError::Contract when the spelling is none of the four shapes.

fn window_end(spelling: &str) -> Result<WindowEnd, RungBuildError>

pub fn shape(&self) -> &'static str

The shape’s name, for a refusal.

Trait Implementations

impl Clone for Locator

fn clone(&self) -> Locator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Locator

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

Formats the value using the given formatter.

impl Display for Locator

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

Formats the value using the given formatter.

impl Eq for Locator

impl PartialEq for Locator

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