This module contains some useful utilities copy-and-pasted from the lens library to avoid a dependency which are used internally and also re-exported for convenience

Synopsis

Utilities

rewriteOf :: ASetter a b a b -> (b -> Maybe a) -> a -> b Source #

Identical to Control.Lens.rewriteOf

transformOf :: ASetter a b a b -> (b -> b) -> a -> b Source #

rewriteMOf :: Monad m => LensLike (WrappedMonad m) a b a b -> (b -> m (Maybe a)) -> a -> m b Source #

transformMOf :: Monad m => LensLike (WrappedMonad m) a b a b -> (b -> m b) -> a -> m b Source #

mapMOf :: LensLike (WrappedMonad m) s t a b -> (a -> m b) -> s -> m t Source #

Identical to Control.Lens.mapMOf
