aiofastnet 0.0.2

Fast transport/protocol networking for asyncio

aiofastnet provides highly optimized asyncio loop create_connection and create_server implementations. It is a drop-in replacement for the standard asyncio functions.

Internally, it reimplements parts of CPython’s transport/SSL stack with Cython and C to reduce overhead on hot I/O paths.

Basic Usage

Use it similarly to stdlib asyncio APIs by passing the running loop:

import asyncio
from aiofastnet import create_connection, create_server

class Echo(asyncio.Protocol):
    def connection_made(self, transport):
        self.transport = transport

    def data_received(self, data):
        self.transport.write(data)

async def main():
    loop = asyncio.get_running_loop()

    server = await create_server(loop, Echo, host="127.0.0.1", port=9000)
    transport, protocol = await create_connection(
        loop, Echo, host="127.0.0.1", port=9000
    )

    transport.close()
    server.close()
    await server.wait_closed()

asyncio.run(main())

Status

This project is focused on performance-sensitive asyncio networking and is implemented specifically for CPython.
