Installation
------------
.. code-block:: shell
pip install async_lru
Usage
-----
This package is 100% port of Python built-in function `functools.lru_cache <https://docs.python.org/3/library/functools.html#functools.lru_cache>`_ for `asyncio <https://docs.python.org/3/library/asyncio.html>`_
.. code-block:: python
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
