Constraint

Make-constraint

Basic constructor macro for constraint structures.

Syntax

(make-constraint [:name <name>] 
                 [:cond <cond>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-constraint

(defmacro make-constraint (&rest args)
  (std::make-aggregate 'constraint
                       args '((:name) (:cond))
                       'make-constraint
                       nil))

Function: constraint

(defun constraint (name cond)
  (declare (xargs :guard (svex-p cond)))
  (declare (xargs :guard t))
  (let ((__function__ 'constraint))
    (declare (ignorable __function__))
    (b* ((cond (mbe :logic (svex-fix cond)
                    :exec cond)))
      (std::prod-cons name cond))))
