.. py:data:: NeedMapping

.. py:function:: need_mapping_empty() -> NeedMapping[A]

   Create an emtpy NeedMapping.


.. py:function:: need_mapping_singleton(k: Need, v: A) -> NeedMapping[A]

   Create a NeedMapping containing a single (k, v) entry.


.. py:function:: need_mapping_insert(m: NeedMapping[A], k: Need, v: A) -> None

   Insert (k, v) into m.  Replaces any existing entry for k.


.. py:function:: need_mapping_get(m: NeedMapping[A], k: Need) -> Optional[A]

   Get the value associated with need k, or None if k is not found.


.. py:function:: need_mapping_find(m: NeedMapping[A], k: Need) -> A

   Get the value associated with need k.  Raise an exception if it is not found.
