pub struct TransactionManager;

Manages persisted KV transactions for CLI usage.

Implementations

impl TransactionManager

pub fn validate_read_at(db: &Database, point: &ReadAtPoint) -> ReadAtResult<()>

Checks the selected backend’s read-at eligibility before a remote worker attempts to open a fenced SQL session. This is distinct from persisted CLI transaction metadata and never uses its wall-clock start time.

pub fn read_at_capability(db: &Database) -> ReadAtCapability

Returns the selected backend’s explicit read-at capability.

pub fn begin_with_timeout(db: &Database, timeout: Duration) -> Result<String>

Begins a new transaction with the given timeout and returns its ID.

pub fn get_info(db: &Database, txn_id: &str) -> Result<TransactionInfo>

Retrieves persisted transaction metadata.

pub fn is_expired(db: &Database, txn_id: &str) -> Result<bool>

Checks whether a transaction has expired.

pub fn get(db: &Database, txn_id: &str, key: &[u8]) -> Result<Option<Vec<u8>>>

Retrieves a key within the specified transaction.

pub fn put(db: &Database, txn_id: &str, key: &[u8], value: &[u8]) -> Result<()>

Stages a put operation within the specified transaction.

pub fn delete(db: &Database, txn_id: &str, key: &[u8]) -> Result<()>

Stages a delete operation within the specified transaction.

pub fn commit(db: &Database, txn_id: &str) -> Result<()>

Commits staged writes and finalizes the transaction.

pub fn rollback(db: &Database, txn_id: &str) -> Result<()>

Rolls back staged writes and removes transaction metadata.
