Enum FutureContract 

#[non_exhaustive]
pub enum FutureContract {
    Month {
        year: i32,
        month: u32,
    },
    Window {
        start: NaiveDate,
        end: NaiveDate,
    },
}

Which listed contract a futures rung is quoted on.

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.

Month

The contract delivering in year-month, its reference window read off the template’s rule (IMM quarter or calendar month).

Fields

year: i32

The delivery year.

month: u32

The delivery month, 1 to 12.

Window

An explicit reference window, for a contract the template’s rule does not describe.

Fields

start: NaiveDate

The accrual start.

end: NaiveDate

The accrual end, strictly after the start.

Implementations

impl FutureContract

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

A contract from its IMM code — the month letters and two-digit year a quote sheet prints, DEC26 — or a YYYY-MM spelling.

Errors

RungBuildError::Contract naming the spelling.

pub fn label(&self) -> String

The spelling a ladder labels this contract by: its IMM code for a delivery month (DEC26), the window’s dates otherwise.

Trait Implementations

impl Clone for FutureContract

fn clone(&self) -> FutureContract

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FutureContract

impl Debug for FutureContract

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

Formats the value using the given formatter.

impl Eq for FutureContract

impl PartialEq for FutureContract

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