type Left = Connection L Source #
type Right = Connection R Source #
type Triple a b = (Left a b, Right a b) Source #
A constraint kind representing an adjoint triple of Galois connections.
fromInteger :: ConnInteger a => Integer -> a Source #
A replacement for the version in base.
Usable in conjunction with RebindableSyntax:
fromRational :: forall a. ConnRational a => Rational -> a Source #
A replacement for the version in base.
Usable in conjunction with RebindableSyntax:
class (Preorder a, Preorder b) => Connection k a b where Source #
A chain of Galois connections of length 2 or 3.
