C++ named requirements:TrivialClock (od C++11)
The TrivialClock requirements describe the requirements satisfied by several clocks in the chrono library.
Requirements
For a type TC
:
- The type must meet Clock requirements.
- The types
TC::rep
,TC::duration
, andTC::time_point
satisfy the requirements of EqualityComparable, LessThanComparable, DefaultConstructible, CopyConstructible, CopyAssignable, Destructible, and NumericType. - lvalues of the types
TC::rep
,TC::duration
, andTC::time_point
are Swappable. - The function
TC::now()
does not throw exceptions. - The type
TC::time_point::clock
meets the TrivialClock requirements, recursively.
Usage
The following types in the standard library satisfy these requirements:
