Struct SQLiteConnection 

pub struct SQLiteConnection { /* private fields */ }

Wrapper for a SQLite sqlite3 connection pointer used by the SQLite driver.

Provides helpers to prepare/execute statements and stream results into tank_core result types.

Implementations

impl SQLiteConnection

pub fn last_error(&self) -> String

Trait Implementations

impl Connection for SQLiteConnection

async fn connect(driver: &SQLiteDriver, url: Cow<'static, str>) -> Result<Self>

Create a connection (or pool) to the given URL.

fn begin(&mut self) -> impl Future<Output = Result<SQLiteTransaction<'_>>>

Begin a transaction scope tied to this connection.

fn sanitize_url( _driver: &Self::Driver, url: Cow<'static, str>, ) -> Result<Url, Error>

where Self: Sized,

fn disconnect(self) -> impl Future<Output = Result<(), Error>>

where Self: Sized,

Disconnect and release the underlying session(s).

impl Executor for SQLiteConnection

type Driver = SQLiteDriver

Associated driver.

async fn do_prepare(&mut self, sql: String) -> Result<Query<SQLiteDriver>>

Actual implementation for prepare.

fn run<'s>( &'s mut self, query: impl AsQuery<SQLiteDriver> + 's, ) -> impl Stream<Item = Result<QueryResult>> + Send

Execute a query, streaming QueryResult (rows or affected counts).

fn accepts_multiple_statements(&self) -> bool

Supports multiple statements per request.

fn driver(&self) -> Self::Driver

where Self: Sized,

Get the driver instance.

fn prepare<'s>( &'s mut self, query: impl AsQuery<Self::Driver> + 's, ) -> impl Future<Output = Result<Query<Self::Driver>, Error>> + Send

Prepare query.

fn fetch<'s>( &'s mut self, query: impl AsQuery<Self::Driver> + 's, ) -> impl Stream<Item = Result<Row, Error>> + Send

Execute a query yielding Row from the resulting stream (filtering out RowsAffected).

fn execute<'s>( &'s mut self, query: impl AsQuery<Self::Driver> + 's, ) -> impl Future<Output = Result<RowsAffected, Error>> + Send

Execute and aggregate affected rows counter.

fn append<'a, E, It>( &mut self, entities: It, ) -> impl Future<Output = Result<RowsAffected, Error>> + Send

where E: Entity + 'a, It: IntoIterator<Item = &'a E> + Send, <It as IntoIterator>::IntoIter: Send,

Insert many entities efficiently.
