class Monomorphicable k where Source
A types which have the monomorphic representation.
Methods
promote :: MonomorphicRep k -> Monomorphic k Source
Promote the monomorphic value to the polymophic one.
demote :: Monomorphic k -> MonomorphicRep k Source
Demote the polymorphic value to the monomorphic representation.
demote' :: Monomorphicable k => k a -> MonomorphicRep k Source
Convinience function to demote polymorphic types into monomorphic one directly.
demoteComposed :: Monomorphicable (f :.: g) => f (g a) -> MonomorphicRep (f :.: g) Source
Demote polymorphic nested types directly into monomorphic representation.
monomorphicCompose :: f (g a) -> Monomorphic (f :.: g) Source
withPolymorhic :: Monomorphicable k => MonomorphicRep k -> (forall a. k a -> b) -> b Source
Apply dependently-typed function to the monomorphic representation.
liftPoly :: Monomorphicable k => (forall a. k a -> b) -> MonomorphicRep k -> b Source
Flipped version of withPolymorhic.
viaPoly :: (Monomorphicable k, Monomorphicable k') => (forall x y. k x -> k' y) -> MonomorphicRep k -> MonomorphicRep k' Source
Demote the function between polymorphic types into the one between monomorphic one.
