Constraint-instance

Make-constraint-instance

Basic constructor macro for constraint-instance structures.

Syntax

(make-constraint-instance [:thmname <thmname>] 
                          [:subst <subst>])

This is the usual way to construct constraint-instance structures. It simply conses together a structure with the specified fields.

This macro generates a new constraint-instance structure from scratch. See also change-constraint-instance, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-constraint-instance

(defmacro make-constraint-instance (&rest args)
  (std::make-aggregate 'constraint-instance
                       args '((:thmname) (:subst))
                       'make-constraint-instance
                       nil))

Function: constraint-instance

(defun constraint-instance (thmname subst)
  (declare (xargs :guard (and (symbolp thmname)
                              (fgl-object-bindings-p subst))))
  (declare (xargs :guard t))
  (let ((__function__ 'constraint-instance))
    (declare (ignorable __function__))
    (b* ((thmname (mbe :logic (acl2::symbol-fix thmname)
                       :exec thmname))
         (subst (mbe :logic (fgl-object-bindings-fix subst)
                     :exec subst)))
      (std::prod-cons thmname subst))))
