Description
|
|
-----------
|
|
*Partial Function* version of :ref:`-mapRouteResult-`.
|
|
|
|
Changes the message the inner route sends to the responder.
|
|
|
|
The ``mapRouteResult`` directive is used as a building block for :ref:`Custom Directives` to transform the
|
|
:ref:`RouteResult` coming back from the inner route. It's similar to the :ref:`-mapRouteResult-` directive but allows to
|
|
specify a partial function that doesn't have to handle all potential ``RouteResult`` instances.
|
|
|
|
See :ref:`Result Transformation Directives` for similar directives.
