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

base Prelude 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_.

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

base Control.Monad 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_.

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

base Data.Traversable 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_.

mapM :: Monad m => (a -> m b) -> Vector a -> m (Vector b)

vector Data.Vector *O(n)*Apply the monadic action to all elements of the vector, yielding a vector of resultsmapM :: Monad m => (a -> m b) -> Bundle v a -> Bundle m v b

vector Data.Vector.Fusion.Bundle Apply a monadic action to each element of the stream, producing a monadic stream of results
