Value-i64

Change-value-i64

Modifying constructor for value-i64 structures.

Syntax

(change-value-i64 x 
                  [:get <get>])

This is an often useful alternative to make-value-i64.

We construct a new value-i64 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.

                         'change-value-i64
                         'nil))
