=============

---------

.. includecode2:: /../../akka-http/src/main/scala/akka/http/scaladsl/server/directives/BasicDirectives.scala
   :snippet: mapInnerRoute

Description
-----------
Changes the execution model of the inner route by wrapping it with arbitrary logic.

with any other route. Usually, the returned route wraps the original one with custom execution logic.
