GTest change output of failure

I have written a Parameterized Gtest using a struct I made as the parameter value. When the test fails it writes a byte object of the struct like so:

[  FAILED  ] RulesNoProcessing/StressTest.MainTest/2, where GetParam() = 
             40-byte object <01-12 00-00 02-00 00-00 F4-01 00-00 ...>.

Is there anyway way that I can customize the output? I know that there is predicate formats for assertions but I need to do something similar with the actual outcome of the test. If anyone can I help I would really appreciate it!

You have to override the "operator <<", for example

struct Row
{
  int window;
  int osmap;
  friend std::ostream& operator<<(std::ostream& os, const Row& bar) {
  return os << "w = " << bar.window << ", opsmap= " << bar.osmap;  // whatever needed to print
  }
};

Look this for more info https://github.com/google/googletest/blob/master/googletest/docs/advanced.md#teaching-googletest-how-to-print-your-values
