Trait Implementations

impl Connection for SqliteConnection

type Backend = Sqlite

The backend this type connects to

type TransactionManager = AnsiTransactionManager

The transaction manager implementation used by this connection

fn establish(url: &str) -> Result<SqliteConnection, ConnectionError>

Establishes a new connection to the database

fn execute_returning_count<T>(&mut self, source: &T) -> Result<usize, Error>

where T: QueryFragment<<SqliteConnection as Connection>::Backend> + QueryId,

Execute a single SQL statements given by a query and return number of affected rows

fn transaction_state( &mut self, ) -> &mut <<SqliteConnection as Connection>::TransactionManager as TransactionManager<SqliteConnection>>::TransactionStateData

Get access to the current transaction state of this connection

fn instrumentation(&mut self) -> &mut (dyn Instrumentation + 'static)

Get the instrumentation instance stored in this connection

fn set_instrumentation(&mut self, _instrumentation: impl Instrumentation)

Set a specific Instrumentation implementation for this connection

fn transaction<T, E, F>(&mut self, f: F) -> Result<T, E>

where F: FnOnce(&mut Self) -> Result<T, E>, E: From<Error>,

Executes the given function inside of a database transaction

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

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

fn test_transaction<T, E, F>(&mut self, f: F) -> T

where F: FnOnce(&mut Self) -> Result<T, E>, E: Debug,

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

impl LoadConnection for SqliteConnection

type Cursor<'conn, 'query> = Cursor

The cursor type returned by LoadConnection::load

type Row<'conn, 'query> = Row

The row type used as Iterator::Item for the iterator implementation of LoadConnection::Cursor

fn load<'conn, 'query, T>( &'conn mut self, source: T, ) -> Result<<SqliteConnection as LoadConnection>::Cursor<'conn, 'query>, Error>

where T: Query + QueryFragment<<SqliteConnection as Connection>::Backend> + QueryId + 'query, <SqliteConnection as Connection>::Backend: QueryMetadata<<T as Query>::SqlType>,

Executes a given query and returns any requested values

impl SimpleConnection for SqliteConnection

fn batch_execute(&mut self, query: &str) -> Result<(), Error>

Execute multiple SQL statements within the same string.
