string_category

Conversion category for strings.

Synopsis

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

struct string_category;

Description

By default a type is considered a string if it is convertible to string_view.

Users can specialize conversion_category_for for their own types if they want them to be treated as strings. For example:

namespace boost {
namespace json {

template <>
struct conversion_category_for<your::string>
{
    using type = string_category;
};

} // namespace boost
} // namespace json

Matching Types

string, string_view, std::string, std::string_view.

Convenience header <boost/json.hpp>.
