User data

data UserData Source #

Information we keep around during interface file serialization/deserialization. Namely we keep the functions for serializing and deserializing Names and FastStrings. We do this because we actually use serialization in two distinct settings,

  • When serializing interface files themselves
  • When computing the fingerprint of an IfaceDecl (which we computing by hashing its Binary serialization)

These two settings have different needs while serializing Names:

  • Names in interface files are serialized via a symbol table (see Note [Symbol table representation of names] in BinIface).
  • During fingerprinting a binding Name is serialized as the OccName and a non-binding Name is serialized as the fingerprint of the thing they represent. See Note [Fingerprinting IfaceDecls] for further discussion.
