Module Contents

.. py:data:: logger

.. py:class:: BagOfHoldingH5FileBackend

   Bases: :py:obj:`fleche.storage.file.FileStorage`


   File-based storage backend using pickle.

   Stores objects on the filesystem.


   .. py:method:: __post_init__()


   .. py:method:: _to_file(value: Any, path: pathlib.Path) -> None


   .. py:method:: _from_file(path: pathlib.Path) -> Any


.. py:class:: ValueBagOfHoldingH5File

   Bases: :py:obj:`fleche.storage.base.ValueMixin`, :py:obj:`fleche.storage.destructuring.DestructuringMixin`, :py:obj:`BagOfHoldingH5FileBackend`


   Bridges :class:`ValueStorage` with :class:`StorageBackend` primitives.

   Implements ``save`` and ``load`` using ``put`` and ``get``.
   Concrete classes inherit from this and a :class:`StorageBackend`
   implementation to get a fully functional value storage.


.. py:class:: CallBagOfHoldingH5File

   Bases: :py:obj:`fleche.storage.base.CallMixin`, :py:obj:`BagOfHoldingH5FileBackend`


   Bridges :class:`CallStorage` with :class:`StorageBackend` primitives.

   Implements ``save``, ``load``, and ``query`` using ``put`` and ``get``,
   deriving the storage key from the call's lookup key.  ``transform`` is
   inherited from :class:`CallStorage`.

   Concrete classes inherit from this and a :class:`StorageBackend`
   implementation to get a fully functional call storage.
