Synopsis

Documentation

class ShowD f whereSource

Signature printing. An instance ShowD f gives rise to an instance Show (Term f).

Instances

(ShowD f, Show p) => ShowD (:&: f p) 
(ShowD f, ShowD g) => ShowD (:+: f g) 
(Difunctor f, ShowD f) => ShowD (Cxt h f)

From an ShowD difunctor an ShowD instance of the corresponding term type can be derived.
