1. setOf :: Hashable a => Getting (HashSet a) s a -> s -> HashSet a

   lens	Data.HashSet.Lens

   Construct a set from a Getter, Fold, Traversal, Lens or Iso.

   setOf :: Hashable a         => Getter s a     -> s -> HashSet a
   setOf :: (Eq a, Hashable a) => Fold s a       -> s -> HashSet a
   setOf :: Hashable a         => Iso' s a       -> s -> HashSet a
   setOf :: Hashable a         => Lens' s a      -> s -> HashSet a
   setOf :: (Eq a, Hashable a) => Traversal' s a -> s -> HashSet a
   

2. setmapped :: (Eq j, Hashable j) => IndexPreservingSetter (HashSet i) (HashSet j) i j

   lens	Data.HashSet.Lens

   This Setter can be used to change the type of a HashSet by mapping the elements to new values. Sadly, you can't create a valid Traversal for a Set, but you can manipulate it by reading using folded and reindexing it via setmapped.

3. setOf :: Getting IntSet s Int -> s -> IntSet

   lens	Data.IntSet.Lens

   Construct an IntSet from a Getter, Fold, Traversal, Lens or Iso.

   >>> setOf folded [1,2,3,4]
   fromList [1,2,3,4]
   

   >>> setOf (folded._2) [("hello",1),("world",2),("!!!",3)]
   fromList [1,2,3]
   

   setOf :: Getter s Int     -> s -> IntSet
   setOf :: Fold s Int       -> s -> IntSet
   setOf :: Iso' s Int       -> s -> IntSet
   setOf :: Lens' s Int      -> s -> IntSet
   setOf :: Traversal' s Int -> s -> IntSet
   

4. setmapped :: IndexPreservingSetter' IntSet Int

   lens	Data.IntSet.Lens

   This Setter can be used to change the contents of an IntSet by mapping the elements to new values. Sadly, you can't create a valid Traversal for an IntSet, because the number of elements might change but you can manipulate it by reading using folded and reindexing it via setmapped.

   >>> over setmapped (+1) (IntSet.fromList [1,2,3,4])
   fromList [2,3,4,5]
   

5. setOf :: Getting (Set a) s a -> s -> Set a

   lens	Data.Set.Lens

   Construct a set from a Getter, Fold, Traversal, Lens or Iso.

   >>> setOf folded ["hello","world"]
   fromList ["hello","world"]
   

   >>> setOf (folded._2) [("hello",1),("world",2),("!!!",3)]
   fromList [1,2,3]
   

   setOf ::          Getter s a     -> s -> Set a
   setOf :: Ord a => Fold s a       -> s -> Set a
   setOf ::          Iso' s a       -> s -> Set a
   setOf ::          Lens' s a      -> s -> Set a
   setOf :: Ord a => Traversal' s a -> s -> Set a
   

6. setmapped :: Ord j => IndexPreservingSetter (Set i) (Set j) i j

   lens	Data.Set.Lens

   This Setter can be used to change the type of a Set by mapping the elements to new values. Sadly, you can't create a valid Traversal for a Set, but you can manipulate it by reading using folded and reindexing it via setmapped.

   >>> over setmapped (+1) (Set.fromList [1,2,3,4])
   fromList [2,3,4,5]
   

7. setCloseOnExecIfNeeded :: CInt -> IO ()

   network	Network.Socket

   Set the close_on_exec flag on Unix. On Windows, nothing is done. Since 2.7.0.0.

8. setNonBlockIfNeeded :: CInt -> IO ()

   network	Network.Socket

   Set the nonblocking flag on Unix. On Windows, nothing is done.

9. setSockOpt :: Storable a => Socket -> SocketOption -> a -> IO ()

   network	Network.Socket

   Set a socket option.

10. setSockOptValue :: Socket -> SocketOption -> SockOptValue -> IO ()

    network	Network.Socket

    Set a socket option value The existential SockOptValue enables things like:

    mapM_ (uncurry $ setSockOptValue sock) [
    (NoDelay, SockOptValue @Int 1)
    , (Linger, SockOptValue (StructLinger 1 0))
    ]
