template <class CharT, class Traits> std::basic_ostream<CharT, Traits>& operator<<(std::basic_ostream<CharT, Traits>& os, const std::chrono::year_month_day_last& ymdl); | (since C++20) |
Outputs a textual representation of ymdl
into os
, as if by os << ymdl.year() << '/' << ymdl.month_day_last();
os
.
This operator<<
is primarily intended for debugging use. When used with non-default stream flags, the output may be surprising:
using namespace std::chrono; auto ymdl = 2001y/2/last; std::cout.width(10); std::cout.fill('-'); std::cout << std::left << ymdl; // may output "2001------/Feb/last"
