scoped_ticker

What is scoped_ticker designed for?
How could I use it my code? Do you have usage examples in the amgcl-library?

scoped_tic does a tic when it is constructed, and does a toc when it goes out of scope. So it measures the duration of the code block it is created in. One of the examples:

amgcl/examples/solver.cpp

           } else { 
        
               auto t = prof.scoped_tic("assembling"); 
        
               rows = sample_problem(vm["size"].as<int>(), val, col, ptr, rhs, vm["anisotropy"].as<double>()); 
        
           }

	} else {
	auto t = prof.scoped_tic("assembling");
	rows = sample_problem(vm["size"].as<int>(), val, col, ptr, rhs, vm["anisotropy"].as<double>());
	}
