Database executor implementations for sqlw.

Provides async database connections with a unified interface.

Features

• sqlite - Rusqlite support via tokio-rusqlite
• turso - Turso/libSQL support (default)
• postgres - PostgreSQL support via bb8 connection pool with tokio-postgres
• mysql - MySQL support via mysql_async

Module Layout

Each backend module is self-contained:

• postgres contains both PostgresExecutor and PostgresRowRef
• mysql contains both MySqlExecutor and MySqlRowRef
• sqlite contains both SqliteExecutor and SqliteRowRef
• turso contains both TursoExecutor and TursoRowRef

Example

use sqlw::{QueryExecutor, query_qmark as query};
use sqlw_backend::turso::TursoExecutor;

let executor = TursoExecutor::new(|| async {
    turso::Builder::new_local("file.db").build().await?
        .connect()
}).await?;

let users: Vec<User> = executor.query_list(query).await?;
