Helper classes

formatter<std::chrono::month>

hash<std::chrono::month> (C++26)

 

Defined in header <chrono>
constexpr bool operator==( const std::chrono::month& x,                            const std::chrono::month& y ) noexcept;	(1)	(since C++20)
constexpr std::strong_ordering operator<=>( const std::chrono::month& x,                                             const std::chrono::month& y ) noexcept;	(2)	(since C++20)

Compare the two std::chrono::month x and y.

The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively.

Return value

1) unsigned(x) == unsigned(y)

2) unsigned(x) <=> unsigned(y)

Example

Run this code

#include <chrono>
 
int main()
{
    constexpr std::chrono::month m1{6}, m2{8};
 
    static_assert
    (
        m1 < m2 && m1 == m1 && m1 <= m2 &&
        m2 > m1 && m2 != m1 && m2 >= m1 &&
        m1 <=> m2 != 0
    );
}
