String input

For string input, the library supports UTF-8, UTF-16, UTF-32 encodings and several string types, including std::basic_string, std::basic_string_view, null-terminated strings of any char type: char, char8_t, char16_t, char32_t, or wchar_t.

Other classes that have a data() function that returns a pointer to one of the char types listed above and a size() function that has an integer return type are also supported (e.g. std::vector<char>).

The ATL/MFC and Qt library string types are supported. To use them you need to include the header files listed in the table below instead of url.h:

Library	Supported string types	Include instead of url.h
ATL/MFC	CSimpleStringT, CStringT, CFixedStringT	url_for_atl.h
Qt	QString, QStringView, QUtf8StringView	url_for_qt.h

Qt example:

#include "upa/url_for_qt.h"
#include <QString>
#include <iostream>

int main() {
    QString str{"http://example.com/"};
    upa::url url{str};
    std::cout << url.href() << '\n';
    return 0;
}
