hashable-1.4.6.0: hashable.cabal
cabal-version: 2.2
name: hashable
version: 1.4.6.0
synopsis: A class for types that can be converted to a hash value
description:
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.

flag integer-gmp
description:
Are we using @integer-gmp@ to provide fast Integer instances? No effect on GHC-9.0 or later.
manual: False
default: True
flag arch-native
description:
Use @-march=native@ when compiling C sources.
You may need to disable this flag if you are building distributable binaries
manual: True
default: True
flag random-initial-seed
description:
Randomly initialize the initial seed on each final executable invocation
This is useful for catching cases when you rely on (non-existent)
stability of hashable's hash functions.
This is not a security feature.
