Struct diesel::connection::AnsiTransactionManager
source · pub struct AnsiTransactionManager { /* private fields */ }
Expand description
An implementation of TransactionManager
which can be used for backends
which use ANSI standard syntax for savepoints such as SQLite and PostgreSQL.
Implementations§
source§impl AnsiTransactionManager
impl AnsiTransactionManager
sourcepub fn begin_transaction_sql<Conn>(
conn: &mut Conn,
sql: &str,
) -> QueryResult<()>where
Conn: Connection<TransactionManager = Self>,
pub fn begin_transaction_sql<Conn>(
conn: &mut Conn,
sql: &str,
) -> QueryResult<()>where
Conn: Connection<TransactionManager = Self>,
Begin a transaction with custom SQL
This is used by connections to implement more complex transaction APIs to set things such as isolation levels. Returns an error if already inside of a transaction.

source§fn commit_transaction(conn: &mut Conn) -> QueryResult<()>
fn commit_transaction(conn: &mut Conn) -> QueryResult<()>
If the transaction fails to commit due to a SerializationFailure
or a
ReadOnlyTransaction
a rollback will be attempted. If the rollback succeeds,
the original error will be returned, otherwise the error generated by the rollback
will be returned. In the second case the connection will be considered broken
as it contains a uncommitted unabortable open transaction.
