  1. sets :: (Profunctor p, Profunctor q, Settable f) => (p a b -> q s t) -> Optical p q f s t a b

    lens Control.Lens.Setter

    Build a Setter, IndexedSetter or IndexPreservingSetter depending on your choice of Profunctor.

    sets :: ((a -> b) -> s -> t) -> Setter s t a b
    

  2. setting :: ((a -> b) -> s -> t) -> IndexPreservingSetter s t a b

    lens Control.Lens.Setter

    Build an index-preserving Setter from a map-like function. Your supplied function f is required to satisfy:

    f idid
    f g . f h ≡ f (g . h)
    
    Equational reasoning:
    setting . overid
    over . settingid
    
    Another way to view sets is that it takes a "semantic editor combinator" and transforms it into a Setter.
    setting :: ((a -> b) -> s -> t) -> Setter s t a b
    

  3. 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
    

  4. 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.

  5. 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
    

  6. 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]
    

  7. 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
    

  8. 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]
    

  9. setCloseOnExecIfNeeded :: CInt -> IO ()

    network Network.Socket

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

  10. setNonBlockIfNeeded :: CInt -> IO ()

    network Network.Socket

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