Usage:: with AtomicWriter(path).open() as f: f.write(...) :param path: The destination filepath. May or may not exist. :param mode: The filemode for the temporary file. This defaults to `wb` in Python 2 and `w` in Python 3. :param overwrite: If set to false, an error is raised if ``path`` exists. Errors are only raised after the file has been written to. Either way, the operation is atomic. :param open_kwargs: Keyword-arguments to pass to the underlying :py:func:`open` call. This can be used to set the encoding when opening files in text-mode. If you need further control over the exact behavior, you are encouraged to subclass.
