...     return 1
...
>>> await bulk_gather([foo(), foo()], limit=200)
(1, 1)
>>> await gather(foo(), foo())
(1, 1)
>>> run_async(gather(foo(), foo()))
(1, 1)

timeit

>>> import time
>>> import anyio
>>> from asyncur import timeit
>>> @timeit
... async def sleep_test():
...     await anyio.sleep(3)
...
>>> await sleep()
sleep_test Cost: 3.0 seconds

>>> @timeit
... def sleep_test2():
...     time.sleep(3.1)
...
>>> sleep_test2()
sleep_test2 Cost: 3.1 seconds

AsyncRedis

from contextlib import asynccontextmanager

from asyncur import AsyncRedis
from fastapi import FastAPI, Request

@asynccontextmanager
async def lifespan(app):
    async with AsyncRedis(app):
        yield

app = FastAPI(lifespan=lifespan)

@app.get('/')
async def root(request: Request) -> list[str]:
    return await AsyncRedis(request).keys()

@app.get('/redis')
async def get_value_from_redis_by_key(request: Request, key: str) -> str:
    value = await AsyncRedis(request).get(key)
    if not value:
        return ''
    return value.decode()

Read Excel File(need to install with xls extra: pip install "asyncur[xls]")

>>> from asycur.xls import load_xls
>>> await load_xls('tests/demo.xlsx')
[{'Column1': 'row1-\\t%c', 'Column2\nMultiLines': 0, 'Column 3': 1, 4: ''}, {'Column1': 'r2c1\n00', 'Column2\nMultiLines': 'r2 c2', 'Column 3': 2, 4: ''}]
