mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()base Prelude 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.
mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()base Control.Monad 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.
mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()base Data.Foldable 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.
mapM_ :: Monad m => (a -> m b) -> Vector a -> m ()vector Data.Vector O(n) Apply the monadic action to all elements of a vector and ignore the results.
mapM_ :: Monad m => (a -> m b) -> Bundle v a -> m ()vector Data.Vector.Fusion.Bundle Apply a monadic action to each element of the stream
mapM_ :: Monad m => (a -> m b) -> Bundle m v a -> m ()vector Data.Vector.Fusion.Bundle.Monadic Execute a monadic action for each element of the Bundle
mapM_ :: (Monad m, Vector v a) => (a -> m b) -> v a -> m ()vector Data.Vector.Generic O(n) Apply the monadic action to all elements of a vector and ignore the results.
mapM_ :: (PrimMonad m, MVector v a) => (a -> m b) -> v (PrimState m) a -> m ()vector Data.Vector.Generic.Mutable O(n) Apply the monadic action to every element of the vector, discarding the results.
mapM_ :: PrimMonad m => (a -> m b) -> MVector (PrimState m) a -> m ()vector Data.Vector.Mutable O(n) Apply the monadic action to every element of the vector, discarding the results.
mapM_ :: (Monad m, Prim a) => (a -> m b) -> Vector a -> m ()vector Data.Vector.Primitive O(n) Apply the monadic action to all elements of a vector and ignore the results.
