Enum DuplicateKeys 

#[non_exhaustive]
pub enum DuplicateKeys {
    Error,
    LastWins,
}

What to do with a duplicate mapping key.

Document and the serde deserializer read it alike.

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.

Error

An error, as YAML 1.2 requires (the default).

LastWins

The last value wins, and a warning with a “first defined here” label is always recorded. Part of Compat::serde_yaml().
