Struct diesel::connection::AnsiTransactionManager

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

pub fn new() -> Self

Create a new transaction manager

pub fn begin_transaction_sql<Conn>(
    &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.
