Apply a monadic transformation to all values in a stream. If you do not need the transformed values, and instead just want the monadic side-effects of running the action, see mapM_. Subject to fusion

Apply a monadic transformation to all elements in a chunked stream.

Apply the action to all values in the stream. Note: if you want to pass the values instead of consuming them, use iterM instead.

Apply the action to all elements in the chunked stream. Note: the same caveat as with mapM_C applies. If you don't want to consume the values, you can use iterM:

iterM (omapM_ f)

Apply the monadic function to each value in the stream, resulting in a foldable value (e.g., a list). Then yield each of the individual values in that foldable value separately. Generalizes concatMapM, mapMaybeM, and mapFoldableM.

Apply the provided monadic mapping function and monoidal combine all values.

Apply the provided monadic mapping function and monoidal combine all elements in the chunked stream.

Apply a monadic monomorphic transformation to all elements in a chunked stream. Unlike mapME, this will work on types like ByteString and Text which are MonoFunctor but not Functor.
