Time Marker Library

A time marker library is a simple tool for time measurements. Just init and mark in all places where you need.

An example of measurement

bool is_simple(size_t number) {
    size_t index = 2;
    do {
        if (number % index == 0) {
            return false;
        }
        ++index;
    } while (index < number);
    return true;
}
mc::timemarker stamp;
for(size_t index = 99999900; index != 100000000; ++index){
    if(is_simple(index) == true){
        std::cout << index << " ";
        stamp.mark();
    }
}
std::cout << std::endl << stamp << std::endl;

Library interface

namespace mc{
    class timemarker{
    public:
        using clock = std::chrono::system_clock;
        using time_point = clock::time_point;
        using duration = clock::duration;

        timemarker();
        virtual ~timemarker();

        void reset();
        void mark();
        void mark(std::string);
        size_t nr_markers() const;
        
        const std::vector<time_point>& markers() const;
        const std::vector<std::string>& labels() const;
        const std::vector<duration>& durations() const;
    };
    
    std::ostream& operator << (std::ostream&, const timemarker&);
}
