WebWhen the Abseil library was open sourced, I started pondering the issue again. Compared to Google's old dense_hash_map which resized at 50% capacity, the new absl::flat_hash_map resizing at 87.5% capacity was more memory friendly, but it still had these significant peaks of memory usage when resizing. WebJan 25, 2012 · So far as I can tell, it doesn't seem possible to get at the hash functors without also pulling in definitions for the various hash tables. At least not without fooling around with library internal headers. Try: #include using __gnu_cxx::hash; or: #include using std::tr1::hash; Share.

"WebWhen you declare the hash map, you say that the key is a pointer, not a string or whatever else the pointer points to.So you can in fact change the contents of the april array to whatever you want, as it's the pointer to april that is the key.. Then when you use the string literal "april" as key, it's the pointer to that literal that is added as a new key. " - Google sparse hash library
