Data.Singletons.TypeRepStar

Description

This module defines singleton instances making Typeable the singleton for the kind *. The definitions don't fully line up with what is expected within the singletons library, so expect unusual results!

Synopsis

Documentation

data family Sing a Source

The singleton kind-indexed data family.

data Sing ((,,,,,) a0 b0 c0 d0 e0 f0) where STuple6 :: (~) ((,,,,,) a b c d e f) z ((,,,,,) a b c d e f n n n n n n) => Sing a n -> Sing b n -> Sing c n -> Sing d n -> Sing e n -> Sing f n -> Sing ((,,,,,) a b c d e f) z
data Sing ((,,,,,,) a0 b0 c0 d0 e0 f0 g0) where STuple7 :: (~) ((,,,,,,) a b c d e f g) z ((,,,,,,) a b c d e f g n n n n n n n) => Sing a n -> Sing b n -> Sing c n -> Sing d n -> Sing e n -> Sing f n -> Sing g n -> Sing ((,,,,,,) a b c d e f g) z

Here is the definition of the singleton for *:

data instance Sing (a :: *) where
  STypeRep :: Typeable a => Sing a

Instances for SingI, SingKind, SEq, SDecide, and TestCoercion are also supplied.
