Metafunction that computes the return type of the unpack_expr()
function, within the specified domain.
Use the result_of::make_expr<>
metafunction to compute the return type of the make_expr()
function.
typedef detail::unpack_expr_< Tag , Domain , Sequence , fusion::result_of::size<Sequence>::type::value >::type boost::proto::result_of::unpack_expr< Tag, Domain, Sequence, typename Domain::proto_is_domain_ >::type |
Let S
be the type of a Fusion Random Access Sequence equivalent to Sequence
.
Then type
is the same as result_of::make_expr<Tag, Domain, fusion::result_of::value_at_c<S, 0>::type, ... fusion::result_of::value_at_c<S, N-1>::type>::type
, where N
is the size of S
.
