anyio-cysqlite 0.2.0

a anyio and cysqlite library

anyio-cysqlite

A Bidning for cysqlite that makes the database asynchronous with any asynchronous library that can be binded to anyio meaning that it will work with many server implementations and applications including FastAPI, Starlette and Litestar to name a few server libraries.

from anyio_cysqlite import connect


async def main():
    async with await connect("cysqlite.db") as db:
        await db.execute('create table IF NOT EXISTS data (k, v)')

        async with db.atomic():
            await db.executemany('insert into data (k, v) values (?, ?)',
                           [(f'k{i:02d}', f'v{i:02d}') for i in range(10)])
            print(await db.last_insert_rowid())  # 10.

        curs = await db.execute('select * from data')
        async for row in curs:
            print(row)  # e.g., ('k00', 'v00')

        # We can use named parameters with a dict as well.
        row = await db.execute_one('select * from data where k = :key and v = :val',
                             {'key': 'k05', 'val': 'v05'})
        print(row)  # ('k05', 'v05')

        await db.close()

if __name__ == "__main__":
    import anyio
    anyio.run(main)

Updated functionality is better

When it comes to database execution updated functionality normally results in better performance such as providing wrappers for atomic, transaction, and savepoint functions which the standard sqlite3 library doesn't currently have. Instead of having a completely seperate thread for the database all operations are done using the anyio's CapacityLimiter and run_sync making the database less resource heavy.

Batteries included

Unlike cysqlite (As of currently), this library retains access to typehints right out of the box making the library less of a function and attribute guessing game.
