ser_error(std::error_code ec, std::size_t position);

ser_error(std::error_code ec,
                    std::size_t line,
                    std::size_t column);

ser_error(const ser_error& other);

Member functions

std::size_t line() const noexcept

Returns the line number to the end of the text where the exception occurred. Line numbers start at 1.

std::size_t column() const noexcept

Returns the column number to the end of the text where the exception occurred. Column numbers start at 1.

const char* what() const noexcept

Constructs an error message, including line and column position

Inherited from std::system_error

const std::error_code code() const noexcept

Returns an error code for this exception

Example

#include <jsoncons/json.hpp>

using jsoncons::json;

int main()
{
    string s = "[1,2,3,4,]";
    try 
    {
        jsoncons::json j = jsoncons::json::parse(s);
    } 
    catch(const jsoncons::ser_error& e) 
    {
        std::cout << "Caught ser_error with category " 
                  << e.code().category().name() 
                  << ", code " << e.code().value() 
                  << " and message " << e.what() << std::endl;
    }
}

Output:

Caught ser_error with category json_input, code 1 and message Unexpected value separator ',' at line 1 and column 10
