Struct mysql_async::Transaction
source · pub struct Transaction<T>(_);
Expand description
This struct represents MySql transaction.
Transaction
it’s a sugar for START TRANSACTION
, ROLLBACK
and COMMIT
queries, so one
should note that it is easy to mess things up calling this queries manually. Also you will get
NestedTransaction
error if you call transaction.start_transaction(_)
.
