# ZipperPull
![data structure](https://github.com/kudzu-forest/elm-zipper-pull/blob/master/materials/data_structure.png)

 This library makes it easier to attach interface as [linear zipper](https://en.wikipedia.org/wiki/Zipper_(data_structure)#Example:_Bidirectional_list_traversal "list zipper") on arbitrary data types including ordinary records.
 Actually, no data correction type is defined in this package: the only functions exposed here is `create`, which returns  not data itself, but a record containing handler functions to treat your data like list zipper. So it is named `ZipperPull`, not Zipper itself.
 This idea (record-of-functions as an interface) is from [edkelly303/elm-any-type-collections](https://package.elm-lang.org/packages/edkelly303/elm-any-type-collections/1.0.0/).
