Struct diesel::connection::AnsiTransactionManager
[−]
[src]
pub struct AnsiTransactionManager { /* fields omitted */ }An implementation of TransactionManager which can be used for backends
which use ANSI standard syntax for savepoints such as SQLite and PostgreSQL.
Methods
impl AnsiTransactionManager[src]
pub fn new() -> Self[src]
Create a new transaction manager
pub fn begin_transaction_sql<Conn>(
&self,
conn: &Conn,
sql: &str
) -> QueryResult<()> where
Conn: SimpleConnection, [src]
&self,
conn: &Conn,
sql: &str
) -> QueryResult<()> where
Conn: SimpleConnection,
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.
