httk.atomistic.storage.stored_properties
========================================

.. py:module:: httk.atomistic.storage.stored_properties

.. autoapi-nested-parse::

   Stored OPTIMADE property declarations for native structure backings.

   The declarations in this module deliberately name the durable record graph,
   not a storage implementation.  In particular, composition predicates use the
   authoritative normalized-composition relation and exact cross multiplication;
   they never compare presentation floats or persist rendered formula strings.

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

.. py:function:: unitcell_structure_properties()

   Build the stored-property declarations for unit-cell records.

   :return: The property declaration map for unit-cell structure records.


.. py:function:: fundamental_domain_structure_properties()

   Build the stored-property declarations for fundamental-domain records.

   :return: The property declaration map for fundamental-domain records.


.. py:function:: asymmetric_unit_structure_properties()

   Build the stored-property declarations for asymmetric-unit records.

   :return: The property declaration map for asymmetric-unit records.


.. py:function:: attach_structure_property_projections(unitcell, fundamental_domain, asymmetric_unit)

   Attach exact-class property declarations to structure record classes.

   :param unitcell: The unit-cell record class to receive its declarations.
   :param fundamental_domain: The fundamental-domain record class to receive its declarations.
   :param asymmetric_unit: The asymmetric-unit record class to receive its declarations.
   :return: ``None`` after attaching the declaration maps.
