Control.Parallel.Strategies.Lens
Description
A Lens or Traversal can be used to take the role of Traversable in
Control.Parallel.Strategies, enabling those combinators to work with
monomorphic containers.

evalTraversal :: LensLike Eval a a b b -> Strategy b -> Strategy aSource
Evaluate the targets of a Lens or Traversal into a data structure
according to the given strategy.
evalTraversable = evalTraversal traverse
evalTraversal = id

evalTraversal :: (b -> Eval b) -> a -> Eval a) -> Strategy b -> Strategy a
parTraversal :: LensLike Eval a a b b -> Strategy b -> Strategy aSource
Evaluate the targets of a Lens or Traversal according into a
data structure according to a given Strategy in parallel.
