Constraint-equal

Make-constraint-equal

Basic constructor macro for constraint-equal structures.

Syntax

(make-constraint-equal [:left <left>] 
                       [:right <right>])

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

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

Definition

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

Macro: make-constraint-equal

(defmacro make-constraint-equal (&rest args)
  (std::make-aggregate 'constraint-equal
                       args '((:left) (:right))
                       'make-constraint-equal
                       nil))

Function: constraint-equal

(defun constraint-equal (left right)
  (declare (xargs :guard (and (expressionp left)
                              (expressionp right))))
  (declare (xargs :guard t))
  (let ((__function__ 'constraint-equal))
    (declare (ignorable __function__))
    (b* ((left (mbe :logic (expression-fix left)
                    :exec left))
         (right (mbe :logic (expression-fix right)
                     :exec right)))
      (cons :equal (list left right)))))
