        **aiofiles** is an Apache2 licensed library, written in Python, for handling local
        disk files in asyncio applications.
        
        Ordinary local file IO is blocking, and cannot easily and portably made
        asynchronous. This means doing file IO may interfere with asyncio applications,
        which shouldn't block the executing thread. aiofiles helps with this by
        introducing asynchronous versions of files that support delegating operations to
        a separate thread pool.
        
        .. code-block:: python
        
            async with aiofiles.open('filename', mode='r') as f:
                contents = await f.read()
            print(contents)
            'My file contents'
        
        Asynchronous iteration is also supported.
        
        .. code-block:: python
        
            async with aiofiles.open('filename') as f:
                async for line in f:
                    ...
        
        Features
        --------
        
        - a file API very similar to Python's standard, blocking API
        - support for buffered and unbuffered binary files, and buffered text files
        - support for ``async``/``await`` (:PEP:`492`) constructs
        
        
        Installation
        ------------
        
        To install aiofiles, simply:
        
        .. code-block:: bash
        
            $ pip install aiofiles
        
        Usage
        -----
        
        Files are opened using the ``aiofiles.open()`` coroutine, which in addition to
        mirroring the builtin ``open`` accepts optional ``loop`` and ``executor``
        arguments. If ``loop`` is absent, the default loop will be used, as per the
        set asyncio policy. If ``executor`` is not specified, the default event loop
        executor will be used.
        
        In case of success, an asynchronous file object is returned with an
        API identical to an ordinary file, except the following methods are coroutines
        and delegate to an executor:
        
        * ``close``
        * ``flush``
        * ``isatty``
        * ``read``
        * ``readall``
        * ``read1``
        * ``readinto``
        * ``readline``
        * ``readlines``
        * ``seek``
        * ``seekable``
        * ``tell``
        * ``truncate``
        * ``writable``
        * ``write``
        * ``writelines``
        
        In case of failure, one of the usual exceptions will be raised.
        
        The ``aiofiles.os`` module contains executor-enabled coroutine versions of
        several useful ``os`` functions that deal with files:
        
        * ``stat``
        * ``sendfile``
        * ``rename``
        * ``remove``
        * ``mkdir``
        * ``rmdir``
        
        Writing tests for aiofiles
        ~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        Real file IO can be mocked by patching ``aiofiles.threadpool.sync_open``
        as desired. The return type also needs to be registered with the
        ``aiofiles.threadpool.wrap`` dispatcher:
        
        .. code-block:: python
        
            aiofiles.threadpool.wrap.register(mock.MagicMock)(
                lambda *args, **kwargs: threadpool.AsyncBufferedIOBase(*args, **kwargs))
        
            async def test_stuff():
                data = 'data'
                mock_file = mock.MagicMock()
        
                with mock.patch('aiofiles.threadpool.sync_open', return_value=mock_file) as mock_open:
                    async with aiofiles.open('filename', 'w') as f:
                        await f.write(data)
        
                    mock_file.write.assert_called_once_with(data)
