    A :class:`importlib.resources.abc.Traversable` interface for zip files.

    Implements many of the features users enjoy from
    :class:`pathlib.Path`.

    Consider a zip file with this structure::

        .
        ├── a.txt
        └── b
            ├── c.txt
            └── d
                └── e.txt

    >>> data = io.BytesIO()
    >>> zf = zipfile.ZipFile(data, 'w')
    >>> zf.writestr('a.txt', 'content of a')
    >>> zf.writestr('b/c.txt', 'content of c')
    >>> zf.writestr('b/d/e.txt', 'content of e')
    >>> zf.filename = 'mem/abcde.zip'

    Path accepts the zipfile object itself or a filename

    >>> path = Path(zf)

    From there, several path operations are available.

    Directory iteration (including the zip file itself):

    >>> a, b = path.iterdir()
    >>> a
    Path('mem/abcde.zip', 'a.txt')
    >>> b
    Path('mem/abcde.zip', 'b/')

    name property:

    >>> b.name
    'b'

    join with divide operator:

    >>> c = b / 'c.txt'
    >>> c
    Path('mem/abcde.zip', 'b/c.txt')
    >>> c.name
    'c.txt'

    Read text:

    >>> c.read_text(encoding='utf-8')
    'content of c'

    existence:

    >>> c.exists()
    True
    >>> (b / 'missing.txt').exists()
    False

    Coercion to string:

    >>> import os
    >>> str(c).replace(os.sep, posixpath.sep)
    'mem/abcde.zip/b/c.txt'

    At the root, ``name``, ``filename``, and ``parent``
    resolve to the zipfile.

    >>> str(path)
    'mem/abcde.zip/'
    >>> path.name
    'abcde.zip'
    >>> path.filename == pathlib.Path('mem/abcde.zip')
    True
    >>> str(path.parent)
    'mem'

    If the zipfile has no filename, such attributes are not
    valid and accessing them will raise an Exception.

    >>> zf.filename = None
    >>> path.name
    Traceback (most recent call last):
    ...
    TypeError: ...

    >>> path.filename
    Traceback (most recent call last):
    ...
    TypeError: ...

    >>> path.parent
    Traceback (most recent call last):
    ...
    TypeError: ...

    # workaround python/cpython#106763

        Construct a Path from a ZipFile or filename.

        Note: When the source is an existing ZipFile object,
        its type (__class__) will be mutated to a
        specialized type. If the caller wishes to retain the
        original type, the caller should either create a
        separate ZipFile object or pass a filename.
