Vttree-context

Make-vttree-context

Basic constructor macro for vttree-context structures.

Syntax

(make-vttree-context [:ctx <ctx>] 
                     [:subtree <subtree>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

                       args '((:ctx) (:subtree))
                       'make-vttree-context
                       nil))

Function: vttree-context

(defun vttree-context (ctx subtree)
  (declare (xargs :guard (vttree-p subtree)))
  (declare (xargs :guard t))
  (let ((__function__ 'vttree-context))
    (declare (ignorable __function__))
    (b* ((subtree (mbe :logic (vttree-fix subtree)
                       :exec subtree)))
      (cons :context (cons ctx subtree)))))
