GHC.Internal.Fingerprint.Type

Description

Fingerprints for recompilation checking and ABI versioning, and implementing fast comparison of Typeable.

The API of this module is unstable and not meant to be consumed by the general public. If you absolutely must depend on it, make sure to use a tight upper bound, e.g., base < 4.X rather than base < 5, because the interface can change rapidly without much warning.
