operator<<() method from fcf::NTest::TimeDuration class

std::ostream& operator<<(std::ostream& a_stream, const fcf::NTest::TimeDuration& a_td)

Available from version: 1.2.5

Inserts the duration into an output stream.

The operator<< method allows for easy logging of fcf::NTest::TimeDuration objects using standard C++ streams like std::cout.

It supports a special fcf::NTest::Friendly manipulator to switch between human-readable and raw formats directly within the stream expression.

Result

std::ostream&

- Reference to the output stream.

Example: Stream insertion

Demonstrating how to print durations using the stream operator and the Friendly manipulator.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> #include <iostream> FCF_TEST_DEFINE("TimeDemo", "Basics", "StreamInsertion") { fcf::NTest::TimeDuration d(1234567890ULL); // 1. Standard output std::cout << d << std::endl; // 2. Friendly output using the Friendly manipulator std::cout << fcf::NTest::Friendly(true) << d << std::endl; // 3. Raw output using the Friendly manipulator std::cout << fcf::NTest::Friendly(false) << d << std::endl; } int main(int a_argc, char* a_argv[]) { bool error = false; fcf::NTest::cmdRun(a_argc, a_argv, fcf::NTest::CRM_RUN, &error); return error ? 1 : 0; }

Output:
