I'm using the Data.Enumerator library. I'm trying to write a "map"
function that converts an Enumerator of one type to another.
Something like:
mapEnum :: Monad m =>
(a -> b) ->
Enumerator a m r ->
Enumerator b m r
Any hints?
(My exact use case is that I have a ByteString enumerator and I
need to pass it to something that requires a Blaze.Builder
enumerator.)
