1. mapMaybeFieldsWithNulls :: ProductProfunctor p => p (Field SqlBool) (Field SqlBool) -> WithNulls p a b -> WithNulls p (MaybeFields a) (MaybeFields b)

   opaleye	Opaleye.Internal.MaybeFields

   This is only safe if b is OK with having nulls passed through it when they claim to be non-null.

2. mapIO :: HasCallStack => (a -> IO b) -> Parser a -> Parser b

   opt-env-conf	OptEnvConf

   Apply a computation to the result of a parser This is intended for use-cases like resolving a file to an absolute path. It is morally ok for read-only IO actions but you will have a bad time if the action is not read-only.

3. mapIO :: HasCallStack => (a -> IO b) -> Parser a -> Parser b

   opt-env-conf	OptEnvConf.Parser

   Apply a computation to the result of a parser This is intended for use-cases like resolving a file to an absolute path. It is morally ok for read-only IO actions but you will have a bad time if the action is not read-only.

4. mapMaybeBuilder :: (BuildInstruction a -> Maybe (BuildInstruction b)) -> Builder a -> Builder b

   opt-env-conf	OptEnvConf.Setting

   No documentation available.

5. mapValidationFailure :: (e1 -> e2) -> Validation e1 a -> Validation e2 a

   opt-env-conf	OptEnvConf.Validation

   No documentation available.

6. mapValidationTFailure :: forall (m :: Type -> Type) e1 e2 a . Functor m => (e1 -> e2) -> ValidationT e1 m a -> ValidationT e2 m a

   opt-env-conf	OptEnvConf.Validation

   No documentation available.

7. mapConcurrentlyN :: Traversable t => Int -> (a -> PlotM b) -> t a -> PlotM (t b)

   pandoc-plot	Text.Pandoc.Filter.Plot.Internal

   maps a function, performing at most N actions concurrently.

8. mapFileName :: (String -> String) -> FilePath os ar -> FilePath os ar

   pathtype	System.Path

   No documentation available.

9. mapFileNameF :: Functor f => (String -> f String) -> FilePath os ar -> f (FilePath os ar)

   pathtype	System.Path

   No documentation available.

10. mapFileName :: (String -> String) -> FilePath os ar -> FilePath os ar

    pathtype	System.Path.Generic

    No documentation available.
