1. mapM :: (Traversable t, Monad m) => (a -> m b) -> t a -> m (t b)

   base-compat-batteries	Control.Monad.Compat

   Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see mapM_.

   Examples

   mapM is literally a traverse with a type signature restricted to Monad. Its implementation may be more efficient due to additional power of Monad.

2. mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()

   base-compat-batteries	Control.Monad.Compat

   Map each element of a structure to a monadic action, evaluate these actions from left to right, and ignore the results. For a version that doesn't ignore the results see mapM. mapM_ is just like traverse_, but specialised to monadic actions.

3. mappend :: Monoid a => a -> a -> a

   base-compat-batteries	Data.Monoid.Compat

   An associative operation NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.

4. mapSeverity :: (Severity -> Severity) -> WithSeverity msg -> WithSeverity msg

   co-log-core	Colog.Core.Severity

   Map the given function over the severity of a WithSeverity. This can be useful to operate generically over the severity, for example:

   suppressErrors :: LogAction m (WithSeverity msg) -> LogAction m (WithSeverity msg)
   suppressErrors = cmap (mapSeverity (s -> if s == Error then Warning else s))
   

5. mapBody :: (body0 -> body1) -> T time body0 -> T time body1

   event-list	Data.EventList.Absolute.TimeBody

   No documentation available.

6. mapBodyM :: Monad m => (body0 -> m body1) -> T time body0 -> m (T time body1)

   event-list	Data.EventList.Absolute.TimeBody

   No documentation available.

7. mapCoincident :: Ord time => ([a] -> [b]) -> T time a -> T time b

   event-list	Data.EventList.Absolute.TimeBody

   Apply a function to the lists of coincident events.

8. mapM :: Monad m => (time0 -> m time1) -> (body0 -> m body1) -> T time0 body0 -> m (T time1 body1)

   event-list	Data.EventList.Absolute.TimeBody

   No documentation available.

9. mapM_ :: Monad m => (time -> m ()) -> (body -> m ()) -> T time body -> m ()

   event-list	Data.EventList.Absolute.TimeBody

   No documentation available.

10. mapMaybe :: Num time => (body0 -> Maybe body1) -> T time body0 -> T time body1

    event-list	Data.EventList.Absolute.TimeBody

    No documentation available.
