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.

Instances

TestCoercion * (Sing *) 
SDecide k (KProxy k) => TestEquality k (Sing k) 
data Sing Bool where 
data Sing Ordering where 
data Sing * where 
data Sing Nat where 
data Sing Symbol where 
data Sing () where 
data Sing [a0] where 
data Sing (Maybe a0) where 
data Sing (Either a0 b0) where 
data Sing ((,) a0 b0) where 
data Sing ((,,) a0 b0 c0) where 
data Sing ((,,,) a0 b0 c0 d0) where 
data Sing ((,,,,) a0 b0 c0 d0 e0) where 
data Sing ((,,,,,) a0 b0 c0 d0 e0 f0) where 
data Sing ((,,,,,,) a0 b0 c0 d0 e0 f0 g0) where 

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.
