Get the nextstates field from a svtv-composedata.
(svtv-composedata->nextstates x) → nextstates
This is an ordinary field accessor created by defprod.
Function:
(defun svtv-composedata->nextstates$inline (x) (declare (xargs :guard (svtv-composedata-p x))) (declare (xargs :guard t)) (let ((__function__ 'svtv-composedata->nextstates)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (svex-alistlist-fix (std::prod-car (std::prod-cdr x)))) :exec (std::prod-car (std::prod-cdr x)))))
