philiprehberger-func-timeout

Add a timeout to any function call, sync or async.

Installation

pip install philiprehberger-func-timeout

Usage

from philiprehberger_func_timeout import timeout
import time

@timeout(2.0)
def slow_computation() -> str:
    time.sleep(10)
    return "done"

slow_computation()  # raises TimeoutError after 2 seconds

Async functions

@timeout(1.5)
async def fetch_data(url: str) -> str:
    await asyncio.sleep(10)
    return "data"

await fetch_data("https://example.com")  # raises TimeoutError after 1.5s

Fallback value

@timeout(2.0, fallback="default")
def risky_call() -> str:
    time.sleep(10)
    return "result"

risky_call()  # returns "default" instead of raising

Custom exception

class MyError(Exception):
    def __init__(self, seconds: float) -> None:
        super().__init__(f"Took too long: {seconds}s")

@timeout(3.0, exception=MyError)
def slow() -> None:
    time.sleep(10)

One-shot execution

from philiprehberger_func_timeout import run_with_timeout, async_run_with_timeout
import asyncio, time

# Sync: call any function with a timeout, no decorator required
result = run_with_timeout(time.sleep, 0.01, timeout=1)

# Async: wrap any awaitable
async def main() -> None:
    await async_run_with_timeout(asyncio.sleep(0.01), timeout=1)

asyncio.run(main())

Retry

from philiprehberger_func_timeout import retry

@retry(attempts=3, delay=1.0, backoff=2.0)
def fetch_data(url: str) -> str:
    return requests.get(url).text

result = fetch_data("https://api.example.com/data")
