outcome<T, EC = varies, EP = varies, NoValuePolicy = policy::default_policy<T, EC, EP>>

A type alias to either std_outcome<T, EC = std::error_code, EP = std::exception_ptr, NoValuePolicy = policy::default_policy<T, EC, EP>> (standalone edition) or boost_outcome<T, EC = boost::system::error_code, EP = boost::exception_ptr, NoValuePolicy = policy::default_policy<T, EC, EP>> (Boost edition), and policy::default_policy . This means that outcome<T> uses the appropriate default alias depending on which edition of Outcome is in use.
