Module std::hash

Generic (non-cryptographic) hashing support

The main purpose of this module is to support the hashing functionality required for hashed collections such as HashMap in a generic and algorithm-agnostic fashion. See the Hashable module for how to make a custom type hashable and Hasher for implementing other hashing algorithms.
