The union package

[ Tags: bsd3, data, library ] [ Propose Tags ]

Extensible type-safe unions for Haskell with prisms using modern GHC features. Dual to vinyl records. Unions are also known as corecords or polymorphic variants. Neither requires a Typeable constraint nor uses unsafe coercions at the cost of linear time access (negligible in practice).


Dependencies base (>=4.8 && <4.11), deepseq (==1.4.*), profunctors (>=5.1 && <5.3), tagged (==0.8.*), vinyl (>=0.5 && <0.8) [details]
