Synopsis

Documentation

newtype Trav f Source

A Trav uses an glues together Applicative actions with (*>) in the manner of traverse_ from Data.Foldable. Any values returned by reduced actions are discarded.

Constructors

Trav
Fields getTrav :: f ()

Instances

Apply f => Semigroup (Trav f)
Apply f => Reducer (f a) (Trav f)

newtype App f m Source

A App turns any Apply wrapped around a Semigroup into a Semigroup

Constructors

App
Fields getApp :: f m

Instances

Functor f => Functor (App f)
Apply f => Apply (App f)
(Apply f, Reducer c m) => Reducer (f c) (App f m)
(Apply f, Semigroup m) => Semigroup (App f m)
