## Simple usage

If you look at it, *path operation functions* are declared to be used whenever a *path* and *operation* matches, and then **FastAPI** takes care of calling the function with the correct parameters, extracting the data from the request.

                    RETURN type=kotlin.Nothing from='local final fun <anonymous> (it: kotlin.Int): kotlin.Int declared in <root>.CodeFragment.run'

* If no ranges are involved, then the highest version that is not rejected will be selected.
** If a version declared as `strictly` is lower than that version, selection will fail.
* If ranges are involved:
