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

.. py:class:: VoidBackend

   Bases: :py:obj:`fleche.storage.base.StorageBackend`


   A concrete implementation of Storage that does not store anything.


   .. py:method:: put(value: Any, key: fleche.digest.Digest) -> fleche.digest.Digest


   .. py:method:: get(key: fleche.digest.Digest) -> Any


   .. py:method:: list() -> Iterable[fleche.digest.Digest]


   .. py:method:: _evict(key: fleche.digest.Digest) -> None


   .. py:method:: _contains(key: fleche.digest.Digest) -> bool


.. py:class:: ValueVoid

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


   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:: CallVoid

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


   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.
