row-types: Open Records and Variants
This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
This package uses closed type families and type literals to implement open records and variants. The core is based off of the CTRex package, but it additionally includes polymorphic variants and a number of additional functions. That said, it is not a proper superset of CTRex as it specifically forbids records from having more than one element of the same label.

[back to package description]Row-Types
Row-types is a library of open records and variants for Haskell using closed type families and type literals (among other things...). See examples/Examples.lhs for a literate Haskell file that functions as an overview of how this library can be used, and check out the website for further examples.
Available on Hackage.
This work is a branch from CTRex [1,2] with other inspiration from data-diverse [3]. My thanks to the authors and contributors of those libraries!
