WebApr 25, 2024 · The standard template library (STL) for C++ provides hash tables via std::unordered_map and std::unordered_set. The standard guarantees reference stability: References and pointers to the keys and values in the hash table must remain valid until the corresponding key is removed. Webcc_hash_table is parametrized by Hash_Fn and Comb_Hash_Fn, a hash functor and a combining hash functor, respectively. In general, Comb_Hash_Fn is considered a range-hashing functor. cc_hash_table synthesizes a ranged-hash function from Hash_Fn and Comb_Hash_Fn (see (1) above).
