Stopwatch

Stopwatch is a header-only class that encapsulates the boilerplate needed to time a block of code using the standard std::chrono infrastructure.

Example

Without further ado, here's a basic example of how the class might be used.

const auto stopwatch = Stopwatch<std::chrono::milliseconds>([&] { FunctionToBeTimed(); });

std::cout << "Task completed in " << stopwatch.GetElapsedTime().count() << " "
          << stopwatch.GetUnitsAsString() << ".\n";

The snippet above will result in the following output being printed to the console, assuming that FunctionToBeTimed() completed in exactly one second:

Task completed in 1000 milliseconds.

The following std::chrono types are support as units of measurement:

• std::chrono::nanoseconds
• std::chrono::microseconds
• std::chrono::milliseconds
• std::chrono::seconds
• std::chrono::minutes
• std::chrono::hours

That's it, folks.
