StringZilla can be used to accelerate containers with std::string keys, by overriding the default comparator and hash functions.std::map<std::string, int, sz::string_view_less> sorted_words; std::unordered_map<std::string, int, sz::string_view_hash, sz::string_view_equal_to> words;...
operator<(), operator>(), operator<=(), and operator>=() were previously available for the std::unordered_map and stdext::hash_map families of containers, although their implementations were not useful. These non-standard operators have been removed in Visual C++ in Visual Studio 2012. Addit...

map与multimap其实与set与multiset差不多,set与multiset是一种特殊的map与multimap。其再命名空间的定义如下: namespace std{ template <class key, class t, class compare = less<key>, class allocator = allocator<pair<const key, t>>> class map ; ...
