std::chrono::operator<< (std::chrono::weekday_indexed)
From cppreference.com
< cpp | chrono | weekday indexed
template <class CharT, class Traits> std::basic_ostream<CharT, Traits>& |
(since C++20) | |
Outputs a textual representation of wdi
into the stream os
, as if by:
os << wdi.weekday() << '[' << wdi.index(); if(wdi.index() >=1 && wdi.index <= 5) { os << ']'; } else { os << " is not a valid index]"; }
Return value
os
.
Notes
This operator<<
is primarily intended for debugging use. When used with non-default stream flags, the output may be surprising:
auto wdi = std::chrono::Sunday[1]; std::cout.width(10); std::cout.fill('-'); std::cout << std::left << wdi; // may output "Sun-------[1]"
