boost::urls::grammar::ci_less
A case-insensitive less predicate for strings
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)
