Enum CasDecision 

#[non_exhaustive]
pub enum CasDecision {
    Committed,
    Conflict(ConflictReason),
    Invalid(&'static str),
}

The outcome of evaluate_cas or evaluate_condition. Invalid is a malformed request (invalid_argument); Conflict is a precondition failure the client can rebase and retry (failed_precondition).

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.

Committed

The write may commit.

Conflict(ConflictReason)

The precondition does not hold.

Invalid(&'static str)

The request is malformed; the message is client-safe.
