mapM :: (Traversable t, Monad m) => (a -> m b) -> t a -> m (t b)mixed-types-num Numeric.MixedTypes.PreludeHiding 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.mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()mixed-types-num Numeric.MixedTypes.PreludeHiding 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.
mappend :: Monoid a => a -> a -> amixed-types-num Numeric.MixedTypes.PreludeHiding 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.
mapLoggingT :: (m a -> n b) -> LoggingT m a -> LoggingT n bmonad-logger-aeson Control.Monad.Logger.Aeson Map the unwrapped computation using the given function.
mapNoLoggingT :: (m a -> n b) -> NoLoggingT m a -> NoLoggingT n bmonad-logger-aeson Control.Monad.Logger.Aeson Map the unwrapped computation using the given function.
