Eoutcome

Change-eoutcome

Modifying constructor for eoutcome structures.

Syntax

(change-eoutcome x 
                 [:cstate <cstate>] 
                 [:values <values>])

This is an often useful alternative to make-eoutcome.

We construct a new eoutcome structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

Macro: change-eoutcome

                         x args

                           (:values . eoutcome->values))
                         'change-eoutcome
                         'nil))
