Encode the argument in it's full length. This is different from many default binary instances which make no guarantee about the actual encoding and might do things use variable length encoding.

Lazy Binary I/O

lazyPut :: Binary a => BinHandle -> a -> IO () Source #

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 GHC.Iface.Binary).
  • 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.
