Init-value-result

Fixtype of initialization values and errors.

This is a sum-of-products (i.e., union) type, introduced by fty::defflexsum.

Members

:err → init-value-result-err

Theorem: not-errorp-when-init-valuep

(defthm not-errorp-when-init-valuep
  (implies (init-valuep x)
           (not (errorp x))))
