labthings_fastapi.dependencies
==============================

.. py:module:: labthings_fastapi.dependencies

.. autoapi-nested-parse::

   Resources that may be requested using annotated types.

   :ref:`actions` often need to access resources outside of the host `.Thing`\ , for
   example invoking actions or accessing properties on other `.Thing`\ s or
   calling methods provided by the server.

   :ref:`dependencies` are a `FastAPI concept`_ that is reused in LabThings to allow
   :ref:`actions` to request resources in a way that plays nicely with type hints
   and is easy to intercept for testing.

   There is more documentation at :ref:`dependencies` for how this works within
   LabThings.
