Struct TransactionRecord 

pub struct TransactionRecord { /* private fields */ }

The storage-facing identity and state of a transaction.

Implementations

impl TransactionRecord

pub const fn new(id: TransactionId, base_snapshot: SnapshotId) -> Self

Create a transaction record in the only valid initial state.

pub const fn with_artifact(self, artifact: BlobId) -> Self

Bind an immutable content-addressed transaction artifact before persistence.

pub const fn id(&self) -> TransactionId

Return the transaction identity.

pub const fn base_snapshot(&self) -> SnapshotId

Return the immutable base snapshot identity.

pub const fn state(&self) -> TransactionState

Return the current persisted state.

pub const fn artifact(&self) -> Option<BlobId>

Return the immutable transaction artifact identity, when one is retained.

pub const fn approval(&self) -> Option<ApprovalGrant>

Return the exact independent approval grant, when one exists.

pub fn transition( &mut self, next: TransactionState, ) -> Result<(), TransitionError>

Apply a valid state transition or leave the record unchanged.

Errors

Returns TransitionError when next is not reachable from the current state.
