Schar-array

Fixtype of (ATC's model of) arrays of type signed char.

This is a product type introduced by fty::defprod.

Fields

elemtype — type
elements — schar-list

Additional Requirements

The following invariant is enforced on the fields:

(and (type-case elemtype :schar) (consp elements))

Theorem: schar-arrayp-alt-def

(defthm schar-arrayp-alt-def
  (equal (schar-arrayp x)
         (and (valuep x)
              (value-case x :array)
              (equal (value-array->elemtype x)
                     (type-schar))
              (schar-listp (value-array->elements x)))))

Theorem: schar-array->elements-alt-def

(defthm schar-array->elements-alt-def
  (implies (schar-arrayp array)
           (equal (schar-array->elements array)
                  (value-array->elements array))))
