Usage example ------------- The context manager is useful in cases when you want to apply timeout logic around block of code or in cases when ``asyncio.wait_for()`` is not suitable. Also it's much faster than ``asyncio.wait_for()`` because ``timeout`` doesn't create a new task. The ``timeout(timeout, *, loop=None)`` call returns a context manager that cancels a block on *timeout* expiring:: async with timeout(1.5): await inner() 1. If ``inner()`` is executed faster than in ``1.5`` seconds nothing happens. 2. Otherwise ``inner()`` is cancelled internally by sending ``asyncio.CancelledError`` into but ``asyncio.TimeoutError`` is raised outside of context manager scope. *timeout* parameter could be ``None`` for skipping timeout functionality. Context manager has ``.expired`` property for check if timeout happens exactly in context manager:: async with timeout(1.5) as cm: await inner() print(cm.expired) The property is ``True`` is ``inner()`` execution is cancelled by timeout context manager. If ``inner()`` call explicitly raises ``TimeoutError`` ``cm.expired`` is ``False``. Installation ------------ :: $ pip install async-timeout The library is Python 3 only! Authors and License ------------------- The module is written by Andrew Svetlov. It's *Apache 2* licensed and freely available. CHANGES ======= 2.0.0 (2017-10-09) ------------------ * Changed `timeout <= 0` behaviour * Backward incompatibility change, prior this version `0` was shortcut for `None` * when timeout <= 0 `TimeoutError` raised faster 1.4.0 (2017-09-09) ------------------ * Implement `remaining` property (#20) * If timeout is not started yet or started unconstrained: `remaining` is `None` * If timeout is expired: `remaining` is `0.0` * All others: roughly amount of time before `TimeoutError` is triggered 1.3.0 (2017-08-23) ------------------ * Don't suppress nested exception on timeout. Exception context points on cancelled line with suspended `await` (#13) * Introduce `.timeout` property (#16) * Add methods for using as async context manager (#9) 1.2.1 (2017-05-02) ------------------ * Support unpublished event loop's "current_task" api. 1.2.0 (2017-03-11) ------------------ * Extra check on context manager exit * 0 is no-op timeout 1.1.0 (2016-10-20) ------------------ * Rename to `async-timeout` 1.0.0 (2016-09-09) ------------------ * The first release.

Usage example ------------- The context manager is useful in cases when you want to apply timeout logic around block of code or in cases when ``asyncio.wait_for()`` is not suitable. Also it's much faster than ``asyncio.wait_for()`` because ``timeout`` doesn't create a new task. The ``timeout(timeout, *, loop=None)`` call returns a context manager that cancels a block on *timeout* expiring:: async with timeout(1.5): await inner() 1. If ``inner()`` is executed faster than in ``1.5`` seconds nothing happens. 2. Otherwise ``inner()`` is cancelled internally by sending ``asyncio.CancelledError`` into but ``asyncio.TimeoutError`` is raised outside of context manager scope. *timeout* parameter could be ``None`` for skipping timeout functionality. Context manager has ``.expired`` property for check if timeout happens exactly in context manager:: async with timeout(1.5) as cm: await inner() print(cm.expired) The property is ``True`` is ``inner()`` execution is cancelled by timeout context manager. If ``inner()`` call explicitly raises ``TimeoutError`` ``cm.expired`` is ``False``. Installation ------------ :: $ pip install async-timeout The library is Python 3 only!

CHANGES ======= 2.0.0 (2017-10-09) ------------------ * Changed `timeout <= 0` behaviour * Backward incompatibility change, prior this version `0` was shortcut for `None` * when timeout <= 0 `TimeoutError` raised faster 1.4.0 (2017-09-09) ------------------ * Implement `remaining` property (#20) * If timeout is not started yet or started unconstrained: `remaining` is `None` * If timeout is expired: `remaining` is `0.0` * All others: roughly amount of time before `TimeoutError` is triggered 1.3.0 (2017-08-23) ------------------ * Don't suppress nested exception on timeout. Exception context points on cancelled line with suspended `await` (#13) * Introduce `.timeout` property (#16) * Add methods for using as async context manager (#9) 1.2.1 (2017-05-02) ------------------ * Support unpublished event loop's "current_task" api. 1.2.0 (2017-03-11) ------------------ * Extra check on context manager exit * 0 is no-op timeout 1.1.0 (2016-10-20) ------------------ * Rename to `async-timeout` 1.0.0 (2016-09-09) ------------------ * The first release.
