Enum Stability 

pub enum Stability {
    FixedOrArchived,
    UnarchivedAndChanging {
        retrieved: AccessDate,
    },
}

Whether a work holds still.

This is the condition APA attaches a retrieval date to, and the date is carried inside the variant that requires it. The two failure modes a separate retrieved field would allow — a changeable work with no retrieval date, and a stable work carrying one that gets emitted anyway — are then not mistakes to catch but sentences that cannot be written.

Deliberately not #[non_exhaustive]: APA’s condition is a yes-or-no question about one work, so the set has exactly two answers.

Variants

FixedOrArchived

The work is fixed, or an archived or versioned copy of what was read still exists. No retrieval date; this is the ordinary case, and APA is explicit that most references carry none.

UnarchivedAndChanging

The work is designed to change over time and is not archived, so the only honest way to cite it is to say when it was read.

Fields

retrieved: AccessDate

When it was read.
