        The cache key is a tuple which can contain any series of
        objects that are hashable and also identifies
        this object uniquely within the presence of a larger SQL expression
        or statement, for the purposes of caching the resulting query.

        The cache key should be based on the SQL compiled structure that would
        ultimately be produced.   That is, two structures that are composed in
        exactly the same way should produce the same cache key; any difference
        in the structures that would affect the SQL string or the type handlers
        should result in a different cache key.

        If a structure cannot produce a useful cache key, the NO_CACHE
        symbol should be added to the anon_map and the method should
        return None.

        The cache key is a tuple which can contain any series of
        objects that are hashable and also identifies
        this object uniquely within the presence of a larger SQL expression
        or statement, for the purposes of caching the resulting query.

        The cache key should be based on the SQL compiled structure that would
        ultimately be produced.   That is, two structures that are composed in
        exactly the same way should produce the same cache key; any difference
        in the structures that would affect the SQL string or the type handlers
        should result in a different cache key.

        The cache key returned by this method is an instance of
        :class:`.CacheKey`, which consists of a tuple representing the
        cache key, as well as a list of :class:`.BindParameter` objects
        which are extracted from the expression.   While two expressions
        that produce identical cache key tuples will themselves generate
        identical SQL strings, the list of :class:`.BindParameter` objects
        indicates the bound values which may have different values in
        each one; these bound parameters must be consulted in order to
        execute the statement with the correct parameters.

        a :class:`_expression.ClauseElement` structure that does not implement
        a :meth:`._gen_cache_key` method and does not implement a
        :attr:`.traverse_internals` attribute will not be cacheable; when
        such an element is embedded into a larger structure, this method
        will return None, indicating no cache key is available.

        The "offline string" is basically the string SQL for the
        statement plus a repr of the bound parameter values in series.
        Whereas the :class:`.CacheKey` object is dependent on in-memory
        identities in order to work as a cache key, the "offline" version
        is suitable for a cache that will work for other processes as well.

        The given ``statement_cache`` is a dictionary-like object where the
        string form of the statement itself will be cached.  This dictionary
        should be in a longer lived scope in order to reduce the time spent
        stringifying statements.
