std::chrono::duration
Template:cpp/chrono/duration/sidebar content

Defined in header <chrono>
template<     class Rep,     class Period = std::ratio<1> > class duration;		(since C++11)

Class template std::chrono::duration represents a time interval. It is represented by a count of ticks and a tick period, where the tick period is the number of seconds from one tick to the next, represented as a compile-time rational constant.

[edit] Member types

Member type	Definition
rep	Rep, an arithmetic type representing the number of ticks
period	Period, an std::ratio type representing the tick period

[edit] Member functions

(constructor)	constructs new duration (public member function)
(destructor)	destructs a duration (public member function)
operator=	assigns the contents (public member function)
count	returns the count of ticks (public member function)
zero	returns the special duration value zero (public member function)
min	returns the special duration value min (public member function)
max	returns the special duration value max (public member function)
operator+ operator-	implements unary + and unary - (public member function)
operator++ operator++(int) operator-- operator--(int)	increments or decrements the tick count (public member function)
operator+= operator-= operator*= operator/= operator%=	implements compound assignment between two durations (public member function)

[edit] Non-member types

This section is incomplete Reason: formatting

Type	Definition
nanoseconds	duration type with Period std::nano
microseconds	duration type with Period std::micro
milliseconds	duration type with Period std::milli
seconds	duration type with Period std::ratio<1>
minutes	duration type with Period std::ratio<60>
hours	duration type with Period std::ratio<3600>

[edit] Non-member functions

std::common_type<std::chrono::duration>	specializes the std::common_type trait (class template specialization)
operator== operator!= operator< operator<= operator> operator>=	compares two durations (public member function)
duration_cast	converts a duration to another, with a different tick interval (public member function)

[edit] Helper classes

treat_as_floating_point	indicates that a duration is convertible to duration with different tick period (class template)
duration_values	constructs zero, min, and max values of a tick count of given type (class template)
