Write a file atomically

:param file: str or :class:`os.PathLike` target to write

:param bool as_file: if True, the yielded object is a :class:File. (eg, what you get with `open(...)`). Otherwise, it will be the temporary file path string

:param kwargs: anything else needed to open the file

:raises: FileExistsError if target exists

Example::

with atomic_write("hello.txt") as f: f.write("world!")
