Enum CasResult 

#[non_exhaustive]
pub enum CasResult {
    Applied(Option<Version>),
    Conflict,
}

The outcome of a scoped compare-and-exchange.

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.

Applied(Option<Version>)

The write was applied. A replacement has a fresh version; deletion has no resulting entry and therefore returns None.

Conflict

The expected version did not match. No current entry is disclosed.
