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

Signature

Description
|
||
-----------
|
||
|
||
**Low level directive** – unless you're sure you need to be working on this low-level you might instead
|
||
want to try the :ref:`-handleRejections-` directive which provides a nicer DSL for building rejection handlers.
|
||
|
||
The ``mapRejections`` directive is used as a building block for :ref:`Custom Directives` to transform a list
|
||
of rejections from the inner route to a new list of rejections.
|
||
|
||
See :ref:`Response Transforming Directives` for similar directives.
|
||
|
