Data.Promotion.Prelude.Bool

Defines promoted functions and datatypes relating to Bool, including a promoted version of all the definitions in Data.Bool.

Because many of these definitions are produced by Template Haskell, it is not possible to create proper Haddock documentation. Please look up the corresponding operation in Data.Bool. Also, please excuse the apparent repeated variable names. This is due to an interaction between Template Haskell and Haddock.

Documentation

type family If k (cond :: Bool) (tru :: k) (fls :: k) :: k where ...

Type-level If. If True a b ==> a; If False a b ==> b

Equations

If k True tru fls = tru

If k False tru fls = fls

Promoted functions from Data.Bool

type family Bool_ (a :: a) (a :: a) (a :: Bool) :: a where ...

Equations

Bool_ fls _tru False = fls

Bool_ _fls tru True = tru

bool_ :: forall a. a -> a -> Bool -> a

The preceding two definitions are derived from the function bool in Data.Bool. The extra underscore is to avoid name clashes with the type Bool.

type family Not (a :: Bool) :: Bool where ...

Equations

type family (a :: Bool) :&& (a :: Bool) :: Bool where ... infixr 3

Equations
