Uint

Make-uint

Basic constructor macro for uint structures.

Syntax

(make-uint [:size <size>] 
           [:value <value>])

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

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

Definition

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

Macro: make-uint

(defmacro make-uint (&rest args)
  (std::make-aggregate 'uint
                       args '((:size) (:value))
                       'make-uint
                       nil))

Function: uint

(defun uint (size value)
  (declare (xargs :guard (and (bit-size-p size) (natp value))))
  (declare (xargs :guard (unsigned-byte-p size value)))
  (let ((__function__ 'uint))
    (declare (ignorable __function__))
    (b* ((size (mbe :logic (bit-size-fix size)
                    :exec size))
         (value (mbe :logic (nfix value) :exec value)))
      (let ((value (mbe :logic (unsigned-byte-fix size value)
                        :exec value)))
        (cons :uint (list size value))))))
