    Make-feat

    Basic constructor macro for feat structures.

    Syntax
    (make-feat [:bits <bits>]) 
    

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

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

    Definition

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

    Macro: make-feat

    (defmacro make-feat (&rest args)
      (std::make-aggregate 'feat
                           args '((:bits))
                           'make-feat
                           nil))

    Function: feat

    (defun feat (bits)
      (declare (xargs :guard (feat-bitsp bits)))
      (declare (xargs :guard t))
      (let ((__function__ 'feat))
        (declare (ignorable __function__))
        (b* ((bits (mbe :logic (feat-bits-fix bits)
                        :exec bits)))
          (list (cons 'bits bits)))))
