mismatched. The files already exist in the destination
directory; therefore, the copy operation was skipped.
1. All files were copied successfully.
2. There are some additional files in the destination directory
that are not present in the source directory. No files were
copied.
3. Some files were copied. Additional files were present. No
failure was encountered.
5. Some files were copied. Some files were mismatched. No failure
was encountered.
6. Additional files and mismatched files exist. No files were

Imports:
>>> from asyncio import run
>>> from shellfish.fs._async import rjson_async, wjson_async
Dictionaries:
>>> data = {'a': 1, 'b': 2, 'c': 3}
>>> fspath = "wjson_async_dict.doctest.json"
>>> run(wjson_async(fspath, data))
19
>>> run(rjson_async(fspath))
{'a': 1, 'b': 2, 'c': 3}
>>> import os; os.remove(fspath)
Lists:
>>> data = {'a': 1, 'b': 2, 'c': 3}
>>> data = list(data.items())
>>> data # has tuples, but will be saved as strings
[('a', 1), ('b', 2), ('c', 3)]
>>> fspath = "wjson_async_list.doctest.json"
>>> run(wjson_async(fspath, data))
25
>>> run(rjson_async(fspath))
[['a', 1], ['b', 2], ['c', 3]]
>>> import os; os.remove(fspath)
