Feat

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

                       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)))))
