Enum YearAmbiguity 

pub enum YearAmbiguity {
    Unambiguous,
    CenturyRequired,
    EraRequired,
    EraAndCenturyRequired,
}

Defines whether the era or century is required to interpret the year.

For example 2024 AD can be formatted as 2024, or even 24, but 1931 AD should not be formatted as 31, and 2024 BC should not be formatted as 2024.
