Expand description
A committed transaction.
Implementations§
Source§impl TransactionCommitted
impl TransactionCommitted
Sourcepub fn committed_version(&self) -> FdbResult<i64>
pub fn committed_version(&self) -> FdbResult<i64>
Retrieves the database version number at which a given transaction was committed.
Read-only transactions do not modify the database when committed and will have a committed version of -1. Keep in mind that a transaction which reads keys and then sets them to their current values may be optimized to a read-only transaction.
Note that database versions are not necessarily unique to a given transaction and so cannot
be used to determine in what order two transactions completed. The only use for this
function is to manually enforce causal consistency when calling set_read_version()
on
another subsequent transaction.
Most applications will not call this function.
Sourcepub fn reset(self) -> Transaction
pub fn reset(self) -> Transaction
Reset the transaction to its initial state.
This will not affect previously committed data.
This is similar to dropping the transaction and creating a new one.
