Enum Duplicates 

#[non_exhaustive]
pub enum Duplicates {
    First,
    Last,
}

Which participating duplicate declaration wins lookup.

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.

First

The first declaration wins.

Last

The last declaration wins.
