Struct foundationdb::TransactionCommitted

pub struct TransactionCommitted { /* private fields */ }

A committed transaction.

Implementations

impl TransactionCommitted

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.

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.
