consign

Completion token adapter used to specify that the completion handler should carry additional values along with it.

template<
    typename CompletionToken,
    typename... Values>
constexpr consign_t< typename decay< CompletionToken >::type, typename decay< Values >::type...> consign(
    CompletionToken && completion_token,
    Values &&... values);

This completion token adapter is typically used to keep at least one copy of an object, such as a smart pointer, alive until the completion handler is called.
