    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

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

    Macro: change-message

    (defmacro change-message (x &rest args)
      (std::change-aggregate 'message
                             x args
                             '((:certificate . message->certificate)
                               (:destination . message->destination))
                             'change-message
                             'nil))
