operator<<(std::basic_string_view) - cppreference.com (original) (raw)

Behaves as a FormattedOutputFunction. After constructing and checking the sentry object, determines the output format padding.

Then stores each character from the resulting sequence seq (the contents of v with padding) to the output stream os as if by calling os.rdbuf()->sputn(seq, n), where n is std::max(os.width(), str.size()).

Finally, calls os.width(0) to cancel the effects of std::setw, if any.

[edit] Exceptions

May throw std::ios_base::failure if an exception is thrown during output.
