Pinst-wide

Change-pinst-wide

Modifying constructor for pinst-wide structures.

Syntax

(change-pinst-wide x 
                   [:width <width>] 
                   [:first <first>] 
                   [:rest <rest>])

This is an often useful alternative to make-pinst-wide.

We construct a new pinst-wide 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.

                           (:first . pinst-wide->first)
                           (:rest . pinst-wide->rest))
