hashable: 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.

Flags
Manual Flags
| Name | Description | Default |
|---|---|---|
| arch-native | Use | Enabled |
| random-initial-seed | 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. | Disabled |
Automatic Flags
| Name | Description | Default |
|---|---|---|
| integer-gmp | Are we using | Enabled |
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
