Module Contents
---------------

.. py:class:: Chunking(*args, **kwds)

   Bases: :py:obj:`enum.Enum`


   Defines how a axis will be chunked

   .. attribute:: NONE

      Axis will not be chunked, accessing any value from this axis will load all values.

   .. attribute:: SINGLE_VALUE

      Axis will be chunked. One chunk per value.


   .. py:attribute:: NONE


   .. py:attribute:: SINGLE_VALUE


.. py:class:: AxisDefinition(keys: list[str], chunking: Chunking)

   
   Defines which axis from a MARS Request form an axis in the Zarr array.

   Also defines if the data is to be chunked.

   :param keys: mars keys that for this axis.
   :type keys: list of str
   :param chunking: Define how this axis shall be chunked
   :type chunking: Chunking
