Get the defstruct field from a atc-tag-info.
(atc-tag-info->defstruct x) → defstruct
This is an ordinary field accessor created by fty::defprod.
Function:
(defun atc-tag-info->defstruct$inline (x) (declare (xargs :guard (atc-tag-infop x))) (declare (xargs :guard t)) (let ((__function__ 'atc-tag-info->defstruct)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (defstruct-info-fix (cdr (std::da-nth 0 x)))) :exec (cdr (std::da-nth 0 x)))))
