Pflat

Make-pflat

Basic constructor macro for pflat structures.

Syntax

(make-pflat [:width <width>] 
            [:what <what>])

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

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

Definition

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

Macro: make-pflat

  (std::make-aggregate 'pflat
                       args '((:width) (:what))
                       'make-pflat
                       nil))

Function: pflat

(defun pflat (width what)
  (declare (xargs :guard (posp width)))
  (declare (xargs :guard t))
  (let ((acl2::__function__ 'pflat))
    (declare (ignorable acl2::__function__))
    (b* ((width (mbe :logic (acl2::pos-fix width)
                     :exec width)))
      (std::prod-cons width what))))
