A case-insensitive equals predicate for strings.
Defined in header <boost/url/grammar/ci_string.hpp>
using ci_equal = see-below;
The function object returns true
when two strings are equal, ignoring case. This is a suitable equality predicate
for unordered containers. The function is defined only for strings containing
low-ASCII characters.
boost::unordered_map< std::string, std::string, ci_hash, ci_equal > m1; std::unordered_map < std::string, std::string, ci_hash, ci_equal > m2; // (since C++20)
