Symantic.Dityped.ADT

EOT (Either of Tuples) to/from ADT (Algebraic Data Type). to produce or consume custom ADT with (<:>) and (<+>).

This is like what is done in generic-sop: https://hackage.haskell.org/package/generics-sop-0.5.1.0/docs/src/Generics.SOP.GGP.html#gSumFrom but using directly Either and Tuples instead of passing by the intermediary GADTs NP and NS.

Type family EoT

type family EoT (adt :: [[*]]) :: * where ...

Equations

EoT '[] = Void

EoT '[ps] = Tuples ps

EoT (ps ': ss) = Either (Tuples ps) (EoT ss)

Type family Tuples

type family Tuples (as :: [*]) :: r :: * where ...

Return the type of snd-nested 2-tuples from the given list of types.

Equations

Tuples (a ': rest) = (a, Tuples rest)
