Enum PublicationDate 

pub enum PublicationDate {
    Year(Year),
    YearMonth {
        year: Year,
        month: Month,
    },
    Full {
        year: Year,
        month: Month,
        day: Day,
    },
}

When a work was published.

An enum rather than a struct of Options so that a day without a month is unrepresentable. Note that this models the precision of a known date, not whether one is known at all — that is Attested’s job, and a Reference::published of Attested::AbsentFromWork is what becomes n.d..

Deliberately not #[non_exhaustive]. APA recognises date shapes this does not carry yet — a season, a range — so the set may well grow. That is the reason for closing it: when it grows, every renderer stops compiling until it says how the new shape is printed, where a wildcard arm would print it as something else. Rendering a date as a date it is not is the failure this whole module is about.

Variants

Year(Year)

The year alone — the commonest case, and all APA requires of most works.

YearMonth

A year and a month.

Fields

year: Year

The year.

month: Month

The month.

Full

A full calendar date.

Fields

year: Year

The year.

month: Month

The month.

day: Day

The day of the month.

Implementations

impl PublicationDate

pub fn names_a_day_that_exists(self) -> bool

Whether this names a day that exists.

Always true for the Year and YearMonth precisions, which cannot name a day at all. For Full it is the question Day cannot answer on its own: Day::new(31) is valid, and February 31 is not.

A method rather than a constructor because making the state unrepresentable means giving this enum an opaque shape — a smart constructor and private fields on a public enum — which is a wider change than the defect warrants. So the formatter refuses instead, which is the module’s other setting and the one it uses wherever a record can be written but not cited.

pub fn year(self) -> Year

The year, whatever the precision. An in-text citation uses only this.
