std::chrono::weekday_indexed
Member functions
weekday_indexed::ok
Nonmember functions
Helper classes
constexpr bool ok() const noexcept;
(since C++20)
Checks if the weekday object and the index stored in *this are both valid.
[edit] Return value
true if weekday().ok() == true and index() is in the range [1, 5]. Otherwise false.
[edit] Example
Run this code
#include <chrono> #include <iostream> int main() { std::cout << std::boolalpha ; std::chrono::weekday_indexed wdi{std::chrono::Tuesday [2]}; std::cout << (wdi.ok()) << ' '; wdi = {std::chrono::weekday (42)[2]}; std::cout << (wdi.ok()) << ' '; wdi = {std::chrono::Tuesday [-4]}; std::cout << (wdi.ok()) << '\n'; }
Output:
true false false
