concat :: Foldable t => t [a] -> [a]

base Prelude The concatenation of all the elements of a container of lists.

concat :: Foldable t => t [a] -> [a]

Cabal Distribution.Compat.Prelude.Internal The concatenation of all the elements of a container of lists.

concat :: (Monad m, Foldable f) => Pipe (f a) a m r

pipes Pipes.Prelude Flatten all Foldable elements flowing downstream

concat :: (Monad m, Foldable f) => Stream (Of (f a)) m r -> Stream (Of a) m r

streaming Streaming.Prelude Make a stream of foldable containers into a stream of their separate elements. This is just

concat str = for str each

>>> S.print $ S.concat (each ["xy","z"]) 'x' 'y' 'z'

Note that it also has the effect of catMaybes, rights 'map snd' and such-like operations.>>> S.print $ S.concat $ S.each [Just 1, Nothing, Just 2] 1 2 >>> S.print $ S.concat $ S.each [Right 1, Left "Error!", Right 2] 1 2 >>> S.print $ S.concat $ S.each [('A',1), ('B',2)] 1 2
