Data.Generics.Str

This module provides the Str data type, which is used by the underlying uniplate and biplate methods. It should not be used directly under normal circumstances.

The Data Type

data Str a

Constructors

Zero

One a

Two (Str a) (Str a)

Instances

Functor Str

Defined in Data.Generics.Str

Methods

fmap :: (a -> b) -> Str a -> Str b

(<$) :: a -> Str b -> Str a

Foldable Str

Defined in Data.Generics.Str

Methods

fold :: Monoid m => Str m -> m

foldMap :: Monoid m => (a -> m) -> Str a -> m

foldMap' :: Monoid m => (a -> m) -> Str a -> m

foldr :: (a -> b -> b) -> b -> Str a -> b

foldr' :: (a -> b -> b) -> b -> Str a -> b

foldl :: (b -> a -> b) -> b -> Str a -> b

foldl' :: (b -> a -> b) -> b -> Str a -> b

foldr1 :: (a -> a -> a) -> Str a -> a

foldl1 :: (a -> a -> a) -> Str a -> a

toList :: Str a -> [a]

null :: Str a -> Bool

length :: Str a -> Int

elem :: Eq a => a -> Str a -> Bool

maximum :: Ord a => Str a -> a

minimum :: Ord a => Str a -> a

sum :: Num a => Str a -> a

product :: Num a => Str a -> a

Traversable Str

Defined in Data.Generics.Str

Methods

traverse :: Applicative f => (a -> f b) -> Str a -> f (Str b)

sequenceA :: Applicative f => Str (f a) -> f (Str a)

mapM :: Monad m => (a -> m b) -> Str a -> m (Str b)

sequence :: Monad m => Str (m a) -> m (Str a)

Eq a => Eq (Str a)

Defined in Data.Generics.Str

Methods

(==) :: Str a -> Str a -> Bool

(/=) :: Str a -> Str a -> Bool

Show a => Show (Str a)

Defined in Data.Generics.Str

Methods

showsPrec :: Int -> Str a -> ShowS

show :: Str a -> String

showList :: [Str a] -> ShowS

strMap :: (a -> b) -> Str a -> Str b

strMapM :: Applicative m => (a -> m b) -> Str a -> m (Str b)

strType :: Str a -> a

Take the type of the method, will crash if called

strList :: Str a -> [a]

Convert a Str to a list, assumes the value was created with listStr

listStr :: [a] -> Str a

Convert a list to a Str

strStructure :: Str a -> ([a], [a] -> Str a)

Transform a Str to a list, and back again, in a structure preserving way. The output and input lists must be equal in length.
