Data.Semigroup.Applicative

Description

Semigroups for working with Applicative Functors.

Synopsis

newtype Traversal f = Traversal {
- getTraversal :: f ()
}
newtype Ap f m = Ap {
- getAp :: f m
}

Documentation

newtype Traversal f Source #

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