ghc-hashable

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.
