std::literals::chrono_literals::operator""y
Defined in header <chrono> | ||
---|---|---|
constexpr std::chrono::year operator ""y(unsigned long long y) noexcept; | (1) | (since C++20) |
Forms a std::chrono::year
literal representing a year in the proleptic Gregorian calendar.
Parameters
y | - | the year value |
Return value
A std::chrono::year
initialized from int(y)
. If y > 32767
, the stored value is unspecified.
Possible implementation
constexpr std::chrono::year operator ""y(unsigned long long y) noexcept { return std::chrono::year(int(y)); } |
Notes
This operator is declared in the namespace std::literals::chrono_literals
, where both literals
and chrono_literals
are inline namespaces. Access to this operator can be gained with using namespace std::literals
, using namespace std::chrono_literals
, and using namespace std::literals::chrono_literals
.
In addition, within the namespace std::chrono
, the directive using namespace literals::chrono_literals;
is provided by the standard library, so that if a programmer uses using namespace std::chrono;
to gain access to the classes in the chrono library, the corresponding literal operators become visible as well.
