Expand description

A persisted transaction state.

Variants (Non-exhaustive)§

This enum is marked as 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.

Created

The transaction record exists but execution has not started.

Running

The untrusted program is executing against virtual state.

VirtualComplete

Virtual execution and canonical diff generation completed.

Denied

Deterministic policy denied the transaction.

AutoApproved

Deterministic policy approved the transaction without a judge.

PendingApproval

The transaction is awaiting an independent approval decision.

Approved

An independent principal approved the exact transaction.

Reserved

The transaction acquired the single-use commit reservation.

Revalidating

Recorded dependencies are being revalidated.

Committing

The trusted committer is applying the canonical diff.

Committed

The committed host state passed verification.

Stale

Revalidation detected stale state before commit.

Expired

Approval expired before reservation.

RecoveryRequired

Recovery is required after an interrupted commit.

Failed

The transaction failed without a successful commit.

Implementations§

impl TransactionState

pub const fn can_transition_to(self, next: Self) -> bool

Return whether next is a valid persisted state transition.

pub const fn is_terminal(self) -> bool

Return whether no normal transition may leave this state.
