Documentation

(<+>) :: Rec f as -> Rec f bs -> Rec f (as ++ bs) infixr 5 Source #

A shorthand for rappend.

(<<*>>) :: RApply rs => Rec (Lift (->) f g) rs -> Rec f rs -> Rec g rs infixl 8 Source #

A shorthand for rapply.

(<<$>>) :: RMap rs => (forall x. f x -> g x) -> Rec f rs -> Rec g rs infixl 8 Source #

A shorthand for rmap.

(<<&>>) :: RMap rs => Rec f rs -> (forall x. f x -> g x) -> Rec g rs Source #

An inverted shorthand for rmap.

data Rec :: (u -> *) -> [u] -> * where Source #

A record is parameterized by a universe u, an interpretation f and a list of rows rs. The labels or indices of the record are given by inhabitants of the kind u; the type of values at any label r :: u is given by its interpretation f r :: *.
