Enum Disambiguation 

#[non_exhaustive]
pub enum Disambiguation {
    Compatible,
    Earlier,
    Later,
    Reject,
}

How a civil (wall-clock) time that does not map cleanly to an instant should be resolved.

This is the TimeZone::ambiguity companion used by DateTime::from_parts_with.

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.

Compatible

The default: in a gap shift the wall time forward, in a fold select the earlier of the two instants.

Earlier

Select the earliest instant. In a gap there is only the shifted forward instant, so this is the same as Compatible there.

Later

Select the latest instant. In a gap there is only the shifted forward instant, so this is the same as Compatible there.

Reject

Reject civil times that are ambiguous or that do not exist with ErrorKind::Ambiguous.
