Description

This module is used to resolve the cyclic we get from defining these classes here rather than in a package upstream. Otherwise we'd get orphaned heads for many instances on the types in transformers and bifunctors.

Synopsis

class Functor f => Apply f where
- (<.>) :: f (a -> b) -> f a -> f b
- (.>) :: f a -> f b -> f b
- (<.) :: f a -> f b -> f a
- liftF2 :: (a -> b -> c) -> f a -> f b -> f c
newtype WrappedApplicative f a = WrapApplicative {
- unwrapApplicative :: f a
}
newtype MaybeApply f a = MaybeApply {
- runMaybeApply :: Either (f a) a
}
(<.*>) :: Apply f => f (a -> b) -> MaybeApply f a -> f b
(<*.>) :: Apply f => MaybeApply f (a -> b) -> f a -> f b
traverse1Maybe :: (Traversable t, Apply f) => (a -> f b) -> t a -> MaybeApply f (t b)
class Apply m => Bind m where
- (>>-) :: m a -> (a -> m b) -> m b
- join :: m (m a) -> m a
apDefault :: Bind f => f (a -> b) -> f a -> f b
returning :: Functor f => f a -> (a -> b) -> f b
class Bifunctor p => Biapply p where
- (<<.>>) :: p (a -> b) (c -> d) -> p a c -> p b d
- (.>>) :: p a b -> p c d -> p c d
- (<<.) :: p a b -> p c d -> p a b

Applyable functors

class Functor f => Apply f where Source #

A strong lax semi-monoidal endofunctor. This is equivalent to an Applicative without pure.

Laws:

(.) <$> u <.> v <.> w = u <.> (v <.> w)
x <.> (f <$> y) = (. f) <$> x <.> y
f <$> (x <.> y) = (f .) <$> x <.> y

The laws imply that .> and <. really ignore their left and right results, respectively, and really return their right and left results, respectively. Specifically,

(mf <$> m) .> (nf <$> n) = nf <$> (m .> n)
(mf <$> m) <. (nf <$> n) = mf <$> (m <. n)

A Monad sans return.

Minimal definition: Either join or >>-

If defining both, then the following laws (the default definitions) must hold:

join = (>>- id)
m >>- f = join (fmap f m)

Laws:

induced definition of <.>: f <.> x = f >>- (<$> x)

Finally, there are two associativity conditions:

associativity of (>>-):    (m >>- f) >>- g == m >>- (\x -> f x >>- g)
associativity of join:     join . join = join . fmap join

These can both be seen as special cases of the constraint that

associativity of (->-): (f ->- g) ->- h = f ->- (g ->- h)
