async-class

Adding abillity to write classes with awaitable initialization function.

Example

import asyncio
from async_class import AsyncClass


class MyAsyncClass(AsyncClass):
    async def __ainit__(self):
        future = self.create_future()
        self.loop.call_soon(future.set_result)
        await future


async def main():
    instance = await MyAsyncClass()
    print(instance)


asyncio.run(main())

Documentation

Module provides metaclasses and some usefule abstractions for writing async code.

TaskStore

TBD

AsyncClass

Base class with task store instance and helpers for simple task management.

AsyncClassBase

Is a base wrapper with metaclass has no additional methods and properties like self.loop and TaskStore related helpers (self.create_task, self.create_future).

import asyncio
from async_class import AsyncClassBase


class MyAsyncClass(AsyncClassBase):
    async def __ainit__(self):
        loop = asyncio.get_event_loop()
        future = loop.create_future()
        loop.call_soon(future.set_result)
        await future


async def main():
    instance = await MyAsyncClass()
    print(instance)


asyncio.run(main())
