static Duration B2bits::HRClock::duration_cast ( duration  d )

inlinestatic

converts a HRClock::duration to a duration of different type (e.g. std::chrono::duration)

template<class Duration >

static duration B2bits::HRClock::duration_cast ( const Duration  d )

inlinestatic

converts a duration of different types(e.g. std::chrono::duration) to HRClock::duration

template<class Duration >

static Duration B2bits::HRClock::elapsed ( time_point  t )

inlinestatic

returns duration elapsed since a particular HRClock::timepoint

static u64 B2bits::HRClock::frequency ( )

staticnoexcept

returns timer frequency - number of timer ticks per second

static time_point B2bits::HRClock::now ( )

staticnoexcept

returns timepoint representing the current value of the clock
