boost::urls::grammar::ci_less
A case-insensitive less predicate for strings
Synopsis
Declared in <boost/url/grammar/ci_string.hpp>
using ci_less = _see-below_;Description
The comparison algorithm implements a case-insensitive total order on the set of all ASCII strings; however, it is not a lexicographical comparison. This is a suitable predicate for ordered containers. The function is defined only for strings containing low-ASCII characters.
boost::container::map< std::string, std::string, ci_less > m1;
std::map< std::string, std::string, ci_less > m2; // (since C++14)
