Implementations§

Source§

impl SqliteConnection

Source

pub fn new(object: Object) -> Result<Self, SqlMiddlewareDbError>

Construct a worker-backed SQLite connection handle.

§Errors

Returns SqlMiddlewareDbError if the background worker thread cannot be spawned.

Source

pub async fn execute_batch( &self, query: String, ) -> Result<(), SqlMiddlewareDbError>

Execute a batch of SQL statements on the worker-owned connection.

§Errors

Propagates any SqlMiddlewareDbError produced while dispatching the command or running the query batch within the worker.

Source

pub async fn execute_select( &self, query: String, params: Vec<Value>, ) -> Result<ResultSet, SqlMiddlewareDbError>

Execute a SQL query and return a ResultSet produced by the worker thread.

§Errors

Returns any SqlMiddlewareDbError encountered while the worker prepares or evaluates the statement, or if channel communication with the worker fails.

Source

pub async fn execute_dml( &self, query: String, params: Vec<Value>, ) -> Result<usize, SqlMiddlewareDbError>

Execute a DML statement (INSERT/UPDATE/DELETE) and return the affected row count.

§Errors

Returns any SqlMiddlewareDbError reported by the worker while executing the statement or relaying the result back to the caller.

Source

pub async fn with_connection<F, R>( &self, func: F, ) -> Result<R, SqlMiddlewareDbError>
where F: FnOnce(&mut Connection) -> Result<R, SqlMiddlewareDbError> + Send + 'static, R: Send + 'static,

Run synchronous rusqlite logic against the underlying worker-owned connection.

§Errors

Propagates any SqlMiddlewareDbError raised while executing the callback or interacting with the worker.

Source

pub async fn prepare_statement( &self, query: &str, ) -> Result<SqlitePreparedStatement, SqlMiddlewareDbError>

Prepare a cached statement on the worker and return a reusable handle.

§Errors

Returns SqlMiddlewareDbError if the worker fails to prepare the statement or if the preparation channel is unexpectedly closed.
