mapRejections

Description

Low level directive – unless you're sure you need to be working on this low-level you might instead want to try the handleRejections directive which provides a nicer DSL for building rejection handlers.

The mapRejections directive is used as a building block for Custom Directives to transform a list of rejections from the inner route to a new list of rejections.

See Transforming the Response for similar directives.
