newtype ReifiedLens s t a b

Reify a Lens so it can be stored safely in a container.

Constructors

Lens

Fields

runLens :: Lens s t a b

type ReifiedLens' s a = ReifiedLens s s a a

type ReifiedLens' = Simple ReifiedLens

newtype ReifiedIndexedLens i s t a b

Reify an IndexedLens so it can be stored safely in a container.

Constructors

IndexedLens

Fields

runIndexedLens :: IndexedLens i s t a b

type ReifiedIndexedLens' i s a = ReifiedIndexedLens i s s a a

type ReifiedIndexedLens' i = Simple (ReifiedIndexedLens i)

newtype ReifiedIndexedTraversal i s t a b

Reify an IndexedTraversal so it can be stored safely in a container.

Constructors

IndexedTraversal

Fields

runIndexedTraversal :: IndexedTraversal i s t a b

type ReifiedIndexedTraversal' i s a = ReifiedIndexedTraversal i s s a a

type ReifiedIndexedTraversal' i = Simple (ReifiedIndexedTraversal i)

newtype ReifiedTraversal s t a b

A form of Traversal that can be stored monomorphically in a container.

Constructors

Traversal

Fields

runTraversal :: Traversal s t a b

type ReifiedTraversal' s a = ReifiedTraversal s s a a

type ReifiedTraversal' = Simple ReifiedTraversal

newtype ReifiedGetter s a

Reify a Getter so it can be stored safely in a container.

This can also be useful when combining getters in novel ways, as ReifiedGetter is isomorphic to '(->)' and provides similar instances.

>>> ("hello","world","!!!")^.runGetter ((,) <$> Getter _2 <*> Getter (_1.to length))
("world",5)

newtype ReifiedFold s a

Reify a Fold so it can be stored safely in a container.

This can also be useful for creatively combining folds as ReifiedFold s is isomorphic to ReaderT s [] and provides similar instances.

>>> ("hello","world")^..runFold ((,) <$> Fold _2 <*> Fold both)
[("world","hello"),("world","world")]
