.. py:class:: ItertoolsMixin

   .. py:attribute:: NO_SIGNATURE_FUNCTIONS


   .. py:attribute:: NO_KWARGS_FUNCTIONS


   .. py:attribute:: iterable
      :value: None



   .. py:method:: use(it_function, **kwargs)

      Provides integration with itertools methods; pass corresponding parameters as kwargs



   .. py:method:: _handle_no_signature_functions(it_function, **kwargs)


   .. py:method:: _handle_no_kwargs_functions(signature, it_function, **kwargs)


   .. py:method:: _handle_default_signature_functions(signature, it_function, **kwargs)


   .. py:method:: tabulate(mapper, start=0)

      Returns function(0), function(1), ...



   .. py:method:: repeat_func(operation, times=None)

      Repeats calls to func with specified arguments



   .. py:method:: ncycles(count=0)

      Returns the query elements n times



   .. py:method:: consume(n=None)

      Advances the iterator n-steps ahead. If n is None, consumes query entirely



   .. py:method:: take_nth(idx, default=None)

      Returns Optional with the nth element of the query or a default value



   .. py:method:: all_equal(key=None)

      Returns True if all elements of the query are equal to each other



   .. py:method:: view(start=0, stop=None, step=None)

      Provides access to a selected part of the query



   .. py:method:: unique(key=None, reverse=False)

      Yields unique elements in sorted order. Supports unhashable inputs



   .. py:method:: _unique(iterable, key=None)
      :staticmethod:



   .. py:method:: unique_just_seen(key=None)

      Yields unique elements, preserving order. Remembers only the element just seen



   .. py:method:: unique_ever_seen(key=None)

      Yields unique elements, preserving order. Remembers all elements ever seen



   .. py:method:: _unique_ever_seen(iterable, key=None)
      :staticmethod:



   .. py:method:: sliding_window(n)

      Collects data into overlapping fixed-length chunks or blocks



   .. py:method:: _sliding_window(iterable, n)
      :staticmethod:



   .. py:method:: grouper(n, *, incomplete='fill', fill_value=None)

      Collects data into non-overlapping fixed-length chunks or blocks



   .. py:method:: _grouper(n, incomplete='fill', fill_value=None)


   .. py:method:: round_robin()

      Visits input iterables in a cycle until each is exhausted



   .. py:method:: _round_robin(iterable)
      :staticmethod:



   .. py:method:: partition(predicate)

      Partitions entries into true and false entries.
      Returns a query of two nested generators



   .. py:method:: subslices()

      Returns all contiguous non-empty sub-slices



   .. py:method:: find_indices(value, start=0, stop=None)

      Returns indices where a value occurs in a sequence or iterable



   .. py:method:: _find_indices(iterable, value, start=0, stop=None)
      :staticmethod:
