Struct Transaction 

pub struct Transaction<'c, DB>
where
    DB: Database,
{ /* private fields */ }

An in-progress database transaction or savepoint.

A transaction starts with a call to Pool::begin or Connection::begin.

A transaction should end with a call to commit or rollback. If neither are called before the transaction goes out-of-scope, rollback is called. In other words, rollback is called on drop if the transaction is still in-progress.

A savepoint is a special mark inside a transaction that allows all commands that are executed after it was established to be rolled back, restoring the transaction state to what it was at the time of the savepoint.

Implementations

impl<'c, DB> Transaction<'c, DB>

where DB: Database,

pub async fn commit(self) -> Result<(), Error>

Commits this transaction or savepoint.

pub async fn rollback(self) -> Result<(), Error>

Aborts this transaction or savepoint.
