availName :: AvailInfo -> NameSource

Just the main name made available, i.e. not the available pieces of type or class brought into scope by the GenAvailInfo

availNames :: AvailInfo -> [Name]Source

All names made available by the availability information

stableAvailCmp :: AvailInfo -> AvailInfo -> OrderingSource

Compare lexicographically

gresFromAvails :: Provenance -> [AvailInfo] -> [GlobalRdrElt]Source

make a GlobalRdrEnv where all the elements point to the same Provenance (useful for hiding imports, or imports with no details).
