Enum TransactionState 

pub enum TransactionState {
    Active,
    Preparing,
    CommitCritical,
    Committed(CommitReceipt),
    Aborted(AbortReason),
}

Formal transaction state (spec §10.2, S1B-001).

Once a commit is CommitCritical its outcome may be durable; from there the only honest transition is Committed(receipt). A post-fence failure (unknown outcome) leaves the state CommitCritical rather than reporting an abort that may be false (spec §4.7).

Variants

Active

Staging writes; no commit attempted.

Preparing

Commit entered: preparation and validation are underway, nothing can be durable yet.

CommitCritical

Commit timestamp assigned and the commit proposal in flight; the outcome may already be durable.

Committed(CommitReceipt)

Durable and published; carries the commit log’s irrevocable receipt.

Aborted(AbortReason)

Ended before the commit fence with nothing durable.
