I would like to import two functions from a module (RatOps) which are in the Datatype (type Rat). How can i do this without editing what is being exported in the module RatOps.

You can import the attributes attr1 and attr2 of the `Rat type with:

import RatOps(Rat(attr1, attr2))

If the Rat type is for example defined as:

data Rat = Rat {
    attr1 :: Bool
  , attr2 :: String
  }

you can import these as items from the Rat type.
