Synopsis

data ((a :: (Type -> Type) -> Type) :* (b :: (Type -> Type) -> Type)) (f :: Type -> Type) = (a f) :* (b f)
newtype Tagged (t :: k) (a :: (Type -> Type) -> Type) (f :: Type -> Type) = Tagged {
- unTagged :: a f
}

Documentation

data ((a :: (Type -> Type) -> Type) :* (b :: (Type -> Type) -> Type)) (f :: Type -> Type) infixr 4 Source #

Infix version of Product. Allows to combine higher-kinded types, and keep them partially applied until needed:

  data User = User { name :: String, age :: Int }
    deriving Generic

  type Config = Nested User :* Single Int

  configOpt :: Config Opt
  configOpt = ...

Constructors

newtype Tagged (t :: k) (a :: (Type -> Type) -> Type) (f :: Type -> Type) Source #

This type adds a type-level phantom tag to a higher-kinded type. Its JSON instance allows using :* with JSONSource.
