impl Connection for SqliteConnection

type Backend = Sqlite

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

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.

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

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

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

fn silence_notices<F: FnOnce() -> T, T>(&self, f: F) -> T

fn begin_transaction(&self) -> QueryResult<()>

fn rollback_transaction(&self) -> QueryResult<()>

fn setup_helper_functions(&self)

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.

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.

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.
