Detailed Description

template<ClockSourceType ClockType>
class detail::StopWatch< ClockType >

A stopwatch utility for measuring elapsed time since construction.

Displays elapsed time as seconds (double) or any specified duration type.

Can use either TSC-based or system clock-based timing, depending on the template parameter ClockType.

Example:

quill::StopWatchTsc swt;
LOG_INFO(logger, "Begin");
std::this_thread::sleep_for(std::chrono::seconds(1));
LOG_INFO(logger, "After 1s, elapsed: {:.6}", swt); // => elapsed: ~1.000000
std::this_thread::sleep_for(std::chrono::milliseconds(500));
LOG_INFO(logger, "After 500ms, elapsed: {}", swt); // => elapsed: ~1.500000
