Description

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

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.Either. Also, please excuse the apparent repeated variable names. This is due to an interaction between Template Haskell and Haddock.

Promoted functions from `Data.Either`

either_ :: (a -> c) -> (b -> c) -> Either a b -> c Source #

type family Either_ (a :: TyFun a c -> Type) (a :: TyFun b c -> Type) (a :: Either a b) :: c where ... Source #

Equations

Either_ f _ (Left x) = Apply f x
Either_ _ g (Right y) = Apply g y

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