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:: with timeout(1.5): yield from 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.
