Description

Semigroups for working with Apply

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

Apply f => Semigroup (Trav f) Source # 

Methods

Methods
