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 ordinary circumstances.

Synopsis

data Str a = Zero | One a | Two (Str a) (Str a) strType :: Str a -> a strList :: Str a -> [a] listStr :: [a] -> Str a strStructure :: Str a -> ([a], [a] -> Str a)

The Data Type

data Str a

Constructors Zero One a Two (Str a) (Str a) Instances Foldable Str Functor Str Traversable Str Show a => Show (Str a)

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.
