Struct sqlx_core::transaction::Transaction

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

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.
