impl Connection for NRConnection

type Backend = Pg

The backend this type connects to

type TransactionManager = AnsiTransactionManager

fn establish(database_url: &str) -> ConnectionResult<NRConnection>

Establishes a new connection to the database

fn execute(&self, query: &str) -> QueryResult<usize>

fn query_by_index<T, U>(&self, source: T) -> QueryResult<Vec<U>> where
    T: AsQuery,
    T::Query: QueryFragment<Pg> + QueryId,
    Pg: HasSqlType<T::SqlType>,
    U: Queryable<T::SqlType, Pg>, 

fn query_by_name<T, U>(&self, source: &T) -> QueryResult<Vec<U>> where
    T: QueryFragment<Pg> + QueryId,
    U: QueryableByName<Pg>, 

fn execute_returning_count<T>(&self, source: &T) -> QueryResult<usize> where
    T: QueryFragment<Pg> + QueryId, 

fn transaction_manager(&self) -> &Self::TransactionManager

fn transaction<T, E, F>(&self, f: F) -> Result<T, E> where
    E: From<Error>,
    F: FnOnce() -> Result<T, E>, 

Executes the given function inside of a database transaction

fn begin_test_transaction(&self) -> Result<(), Error>

Creates a transaction that will never be committed. This is useful for tests. Panics if called while inside of a transaction.

fn test_transaction<T, E, F>(&self, f: F) -> T where
    E: Debug,
    F: FnOnce() -> Result<T, E>, 

Executes the given function inside a transaction, but does not commit it. Panics if the given function returns an error.

impl SimpleConnection for NRConnection

fn batch_execute(&self, query: &str) -> QueryResult<()>

Execute multiple SQL statements within the same string.
