described_enum_category
Conversion category for described enums.
Synopsis
Defined in header <boost/json/conversion.hpp>.
using described_enum_category = std::integral_constant< conversion_category, conversion_category::described_enum >;Description
Described enums are serialized as strings when their value equals to a described enumerator, and as integers otherwise. The reverse operation does not convert numbers to enums values, though, and instead produces an error.
By default a type T is considered a described enum if boost::describe::has_describe_enumerators<T>::value is true.
Users can specialize conversion_category_of for their own enums if they want them to be treated as described enums. For example:
namespace boost { namespace json {
template <>
struct conversion_category_of<your::described_enum>
: described_enum_category
{ };
} }See Also
