Determine if T can be treated like a sequence during conversions.


Defined in header <boost/json/conversion.hpp>

    class T>
struct is_sequence_like

Given t, a glvalue of type T, if

then the trait provides the member constant value that is equal to true. 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 sequences. For example:

namespace boost {
namespace json {

template <>
struct is_sequence_like<your::container> : std::false_type
{ };

} // namespace boost
} // namespace json
Types satisfying the trait

Any SequenceContainer, array types.
