A library for making atomic file writes. Basically it guarantees

that the data is not partially written to the file (hence corrupting

it in case an exception is raised) by writing to a temporary file

that gets renamed and deleted after writing.

.. code-block:: python

    from atomicio.api import atomic_write

    with atomic_write(path) as (r,w):

        for item in r:

            w.write(process(item))

There are many other libraries that provide this functionality in

Python. This library's approach and API is inspired by `fatomic`_

and `python-atomicwrites`_ respectively. So far atomicio has not

been tested on Windows but it shouldn't work because currently,

``os.rename`` does not work on already created files.
