https://travis-ci.org/aio-libs/async_lru.svg?branch=master https://img.shields.io/pypi/v/async_lru.svg https://codecov.io/gh/aio-libs/async_lru/branch/master/graph/badge.svg

Installation

pip install async_lru

Usage

This package is 100% port of Python built-in function functools.lru_cache for asyncio

import asyncio

import aiohttp
from async_lru import alru_cache


@alru_cache(maxsize=32)
async def get_pep(num):
    resource = 'http://www.python.org/dev/peps/pep-%04d/' % num
    async with aiohttp.ClientSession() as session:
        try:
            async with session.get(resource) as s:
                return await s.read()
        except aiohttp.ClientError:
            return 'Not Found'


async def main():
    for n in 8, 290, 308, 320, 8, 218, 320, 279, 289, 320, 9991:
        pep = await get_pep(n)
        print(n, len(pep))

    print(get_pep.cache_info())
    # CacheInfo(hits=3, misses=8, maxsize=32, currsize=8)

    # closing is optional, but highly recommended
    await get_pep.close()


loop = asyncio.get_event_loop()

loop.run_until_complete(main())

loop.close()

Python 3.3+ is required
