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.
