-   :description: This example demonstrates a usage of the FastDepends and Dependency Injector.
-
-
-This example demonstrates how to use ``Dependency Injector`` with `FastDepends <https://github.com/Lancetnik/FastDepends>`_, a lightweight dependency injection framework inspired by FastAPI's dependency system, but without the web framework components.
-
-Basic Usage
------------
-
-The integration between FastDepends and Dependency Injector is straightforward. Simply use Dependency Injector's ``Provide`` marker within FastDepends' ``Depends`` function:
-
-.. code-block:: python
-
-    import sys
-
-    from dependency_injector import containers, providers
-    from dependency_injector.wiring import inject, Provide
-    from fast_depends import Depends
-
-
-    class CoefficientService:
-        @staticmethod
-        def get_coefficient() -> float:
-            return 1.2
-
-
-    class Container(containers.DeclarativeContainer):
-        service = providers.Factory(CoefficientService)
-
-
-    @inject
-    def apply_coefficient(
-        a: int,
-        coefficient_provider: CoefficientService = Depends(Provide[Container.service]),
-    ) -> float:
-        return a * coefficient_provider.get_coefficient()
-
-
-    container = Container()
-    container.wire(modules=[sys.modules[__name__]])

-Few notes on performance
-------------------------
-
-``.wire()`` utilize caching to speed up the wiring process. At the end it clears the cache to avoid memory leaks.
-But this may not always be desirable, when you want to keep the cache for the next wiring
-(e.g. due to usage of multiple containers or during unit tests).
-
-To keep the cache after wiring, you can set flag ``keep_cache=True`` (works with ``WiringConfiguration`` too):

-Integration With Starlette-based Frameworks
-===========================================
-
-This is a `Starlette <https://www.starlette.io/>`_ +
-`Dependency Injector <https://python-dependency-injector.ets-labs.org/>`_ example application
-utilizing `lifespan API <https://www.starlette.io/lifespan/>`_.
-
-.. note::
-
-    Pretty much `any framework built on top of Starlette <https://www.starlette.io/third-party-packages/#frameworks>`_
-    supports this feature (`FastAPI <https://fastapi.tiangolo.com/advanced/events/#lifespan>`_,
-    `Xpresso <https://xpresso-api.dev/latest/tutorial/lifespan/>`_, etc...).
-
-Run
----
-
-Create virtual environment:
-
-.. code-block:: bash
-
-    python -m venv env
-    . env/bin/activate
-
-Install requirements:
-
-.. code-block:: bash
-
-    pip install -r requirements.txt
-
-To run the application do:
-
-.. code-block:: bash
-
-    python example.py
-    # or (logging won't be configured):
-    uvicorn --factory example:container.app
-
-After that visit http://127.0.0.1:8000/ in your browser or use CLI command (``curl``, ``httpie``,
-etc).
