Compares two durations.
1-2) Checks if lhs and rhs are equal, i.e. the number of ticks for the type common to both durations are equal.
3-6) Compares lhs to rhs, i.e. compares the number of ticks for the type common to both durations.
Parameters
| lhs | - | duration on the left-hand side of the operator |
| rhs | - | duration on the right-hand side of the operator |
Return value
Assuming that CT =, then:
std::common_type<std::chrono::duration<Rep1, Period1>,
std::chrono::duration<Rep2, Period2>>::type
1) CT(lhs).count() == CT(rhs).count().
2) !(lhs == rhs).
3) CT(lhs).count() < CT(rhs).count().
4) !(rhs < lhs).
5) rhs < lhs.
6) !(lhs < rhs).

Output:
