Re-exported from Control.Category

id :: forall (a :: k). Category cat => cat a a #

the identity morphism

Re-exported from Control.Arrow

arr :: Arrow a => (b -> c) -> a b c #

Lift a function to an arrow.

first :: Arrow a => a b c -> a (b, d) (c, d) #

Send the first component of the input through the argument arrow, and copy the rest unchanged to the output.

second :: Arrow a => a b c -> a (d, b) (d, c) #

A mirror image of first.

The default definition may be overridden with a more efficient version if desired.

(>>>) :: forall {k} cat (a :: k) (b :: k) (c :: k). Category cat => cat a b -> cat b c -> cat a c infixr 1 #

Left-to-right composition

(<<<) :: forall {k} cat (b :: k) (c :: k) (a :: k). Category cat => cat b c -> cat a b -> cat a c infixr 1 #

Right-to-left composition

(&&&) :: Arrow a => a b c -> a b c' -> a b (c, c') infixr 3 #

Fanout: send the input to both argument arrows and combine their output.

The default definition may be overridden with a more efficient version if desired.

(***) :: Arrow a => a b c -> a b' c' -> a (b, b') (c, c') infixr 3 #

Split the input between the two argument arrows and combine their output. Note that this is in general not a functor.

The default definition may be overridden with a more efficient version if desired.

(Transport t, Monoid a) => Applicative (Churro a t Void) Source #

The Applicative instance allows for pairwise composition of Churro pipelines. Once again this is covariat and the composition occurs on the output transports of the Churros.

The pure method allows for the creation of a Churro yielding a single item.

TODO: Write test to check Monoid return type.
