optiwindnet.fingerprint
=======================

.. py:module:: optiwindnet.fingerprint

.. autoapi-nested-parse::

   Canonical fingerprints for persisted OptiWindNet data.





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

.. py:function:: fingerprint_coordinates(VertexC: numpy.ndarray) -> tuple[bytes, bytes]

   Return the SHA-256 digest and canonical ``.npy`` bytes of ``VertexC``.

   Arrays are normalized to C order before serialization so numerically equal
   C- and Fortran-contiguous inputs have the same digest. Version 3 of NumPy's
   ``.npy`` format is used to match persisted :class:`~optiwindnet.db.NodeSet`
   entries.


.. py:function:: fingerprint_function(function: types.FunctionType) -> dict[str, bytes | str]

   Return the bytecode digest, source filename, and name of ``function``.

   The digest intentionally covers only ``code.co_code`` to preserve existing
   database identities. It is not a complete semantic fingerprint: changes to
   constants, defaults, globals, or closure values may leave the digest
   unchanged.
