Struct persy::Recover [−][src]
Intermediate recover status to select witch transactions to commit or rollback and list witch transactions are in a intermediate state
Example
let mut recover = Persy::recover("./recover_example.persy", Config::new())?; for (tx_id,status) in recover.list_transactions()? { // Check the transaction if can be committed using the tx_id if true { // if so commit the tx recover.commit(tx_id)?; } else { // otherwise roll back it recover.rollback(tx_id)?; } // finalize all the transaction marked to finalize and get a persy instance. } let persy = recover.finalize()?;
Implementations
impl Recover
[src]
pub fn list_transactions(&self) -> PRes<Vec<(TransactionId, RecoverStatus)>>
[src]
List all the transactions found in the log with the current status
pub fn commit(&mut self, tx_id: TransactionId) -> PRes<()>
[src]

pub fn rollback(&mut self, tx_id: TransactionId) -> PRes<()>
[src]
Mark to rollback a transaction that is not yet committed
pub fn status(&self, tx_id: TransactionId) -> PRes<Option<RecoverStatus>>
[src]
Read the status of a transaction in the log
pub fn finalize(self) -> PRes<Persy>
[src]
Recover all the prepared committed transactions that are not marked to rollback
