row-types: Open Records and Variants

[ data, data-structures, library, mit ] [ Propose Tags ] [ Report a vulnerability ]

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.

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 an overview of how this library can be used.

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!
