Examples

import pymaid
from pymaid.net.stream import Stream


class Stream(Stream):

    def data_received(self, data):
        # cannot use asynchronous way since this is in io callback
        self.write_sync(data)


async def main():
    ch = await pymaid.net.serve_stream(
        'tcp://127.0.0.1:8001', transport_class=Stream
    )
    async with ch:
        await ch.serve_forever()


if __name__ == "__main__":
    pymaid.run(main())
import pymaid
from pymaid.net.stream import Stream


class Stream(Stream):

    def init(self):
        self.data_size = 0

    def data_received(self, data):
        self.data_size += len(data)


async def wrapper(address, count):
    stream = await pymaid.net.dial_stream(address, transport_class=Stream)

    for _ in range(count):
        await stream.write(b'a' * 1000)
    stream.shutdown()
    await stream.wait_closed()
    assert stream.data_size == 1000 * count, (stream.data_size, 1000 * count)


async def main():
    tasks = []
    address = 'tcp://127.0.0.1:8001'
    for x in range(100):
        tasks.append(pymaid.create_task(wrapper(address, 1000)))

    # await pymaid.wait(tasks, timeout=args.timeout)
    await pymaid.gather(*tasks)


if __name__ == "__main__":
    pymaid.run(main())
