Num-range

Make-num-range

Basic constructor macro for num-range structures.

Syntax

(make-num-range [:base <base>] 
                [:min <min>] 
                [:max <max>])

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

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

Definition

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

Macro: make-num-range

(defmacro make-num-range (&rest args)
  (std::make-aggregate 'num-range
                       args '((:base) (:min) (:max))
                       'make-num-range
                       nil))

Function: num-range

(defun num-range (base min max)
  (declare (xargs :guard (and (num-base-p base)
                              (natp min)
                              (natp max))))
  (declare (xargs :guard t))
  (let ((__function__ 'num-range))
    (declare (ignorable __function__))
    (b* ((base (mbe :logic (num-base-fix base)
                    :exec base))
         (min (mbe :logic (nfix min) :exec min))
         (max (mbe :logic (nfix max) :exec max)))
      (list (cons 'base base)
            (cons 'min min)
            (cons 'max max)))))
