c++ - conversion from 'size_t' to 'rapidjson::SizeType' -

-

i have c++ example code:

void test() {     rapidjson::document doc;     doc.setobject();      const std::string source = "the quick brown fox jumps on lazy dog";        rapidjson::value source_val;     source_val.setstring( source.c_str(), source.length(), doc.getallocator() );         }

and @ compile time, on x64 platform, warning:

warning c4267: 'argument': conversion size_t rapidjson::sizetype, possible loss of data

how can correctly convert string's length (size_t) rapidjson sizetype?

per documentation:

rapidjson uses 32-bit array/string indices on 64-bit platforms, instead of using size_t. users may override sizetype defining rapidjson_no_sizetypedefine.
