The Data Type

Description

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.

Synopsis

The Data Type

data Str a Source #

Constructors

Zero
One a
Two (Str a) (Str a)

Instances

Functor Str Source #
Methods fmap :: (a -> b) -> Str a -> Str b # (<$) :: a -> Str b -> Str a #
Foldable Str Source #
Methods fold :: Monoid m => Str m -> 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 Source #
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) Source #
Methods (==) :: Str a -> Str a -> Bool # (/=) :: Str a -> Str a -> Bool #
Show a => Show (Str a) Source #
Methods showsPrec :: Int -> Str a -> ShowS # show :: Str a -> String # showList :: [Str a] -> ShowS #

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

strMapM :: Monad m => (a -> m b) -> Str a -> m (Str b) Source #

strType :: Str a -> a Source #

Take the type of the method, will crash if called

strList :: Str a -> [a] Source #

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

listStr :: [a] -> Str a Source #

Convert a list to a Str

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

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