Determine if T
can be treated
like a tuple during conversions.
Defined in header <boost/json/conversion.hpp>
template< class T> struct is_tuple_like;
Provides the member constant value
that is equal to true
, if std::tuple_size<T>::value
is a positive number. Otherwise,
value
is equal to false
.
Users can specialize the trait for their own types if they don't want them to be treated like tuples. For example:
namespace boost { namespace json { template <> struct is_tuple_like<your::tuple> : std::false_type { }; } // namespace boost } // namespace json
Convenience header <boost/json.hpp>
