A class for types that can be converted to a hash value.

This package defines a class, Hashable, for types that can be converted to a hash value. This class exists for the benefit of hashing-based data structures. The package provides instances for basic types and a way to combine hash values.

Hashable is intended exclusively for use in in-memory data structures.

Hashable does not have a fixed standard. This allows it to improve over time.

Because it does not have a fixed standard, different computers or computers on different versions of the code will observe different hash values. As such, hashable is not recommended for use other than in-memory datastructures. Specifically, hashable is not intended for network use or in applications which persist hashed values. For stable hashing use named hashes: sha256, crc32, xxhash etc.
