Message

Change-message

Modifying constructor for message structures.

Syntax

(change-message x 
                [:certificate <certificate>] 
                [:destination <destination>])

This is an often useful alternative to make-message.

We construct a new message 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
