type Backend = Pg
fn establish(database_url: &str) -> ConnectionResult<PgConnection>
Establishes a new connection to the database at the given URL. The URL should be a valid connection string for a given backend. See the documentation for the specific backend for specifics. Read more

fn transaction<T, E, F>(&self, f: F) -> TransactionResult<T, E> where F: FnOnce() -> Result<T, E>
Executes the given function inside of a database transaction. When a transaction is already occurring, savepoints will be used to emulate a nested transaction. Read more
fn begin_test_transaction(&self) -> QueryResult<()>
Creates a transaction that will never be committed. This is useful for tests. Panics if called while inside of a transaction. Read more
fn test_transaction<T, E, F>(&self, f: F) -> T where F: FnOnce() -> Result<T, E>
Executes the given function inside a transaction, but does not commit it. Panics if the given function returns an Err
