This way you write shared code once and **FastAPI** takes care of calling it for your *path operations*.

Notice that you don't have to create a special class and pass it somewhere to **FastAPI** to "register" it or anything similar.

You just pass it to `Depends` and **FastAPI** knows how to do the rest.
