  1. mapM :: Monad m => (b -> m c) -> Unfold m a b -> Unfold m a c

    streamly-core Streamly.Internal.Data.Unfold

    Apply a monadic function to each element of the stream and replace it with the output of the resulting action.

    >>> mapM f = Unfold.mapM2 (const f)
    

  2. mapM :: Monad m => (a -> m b) -> Stream m a -> Stream m b

    vector-stream Data.Stream.Monadic

    Map a monadic function over a Stream

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

    clash-prelude Clash.HaskellPrelude

    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.

  4. mapM :: Monad m => (i -> m o) -> Pipe i o u m u

    conduino Data.Conduino.Combinators

    Map a monadic function to process every input, and yield its output.

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

    control-monad-free Control.Monad.Free

    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.

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

    dimensional Numeric.Units.Dimensional.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_.

    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.

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

    distribution-opensuse OpenSuse.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_.

    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.

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

    distribution-opensuse OpenSuse.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_.

    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.

  9. mapM :: (Functor m, Monad m) => (a -> m b) -> Stream m a -> Stream m b

    leveldb-haskell Data.Stream.Monadic

    No documentation available.

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

    pinch Pinch.Internal.FoldList

    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.
