streaming: A free monad transformer optimized for streaming applications.

[ bsd3, data, library, pipes, streaming ] [ Propose Tags ]

Stream can be used wherever FreeT is used. The compiler is better able to optimize operations written in terms of Stream.

See the examples in Streaming.Prelude for a sense of things. It closely follows Pipes.Prelude, and focused on on employment with a base functor like ((,) a) (here called Of a) which generates effectful sequences or producers - Pipes.Producer, Conduit.Source, IOStreams.InputStream, IOStreams.Generator and the like.

Interoperation with pipes is accomplished with this isomorphism, which uses Pipes.Prelude.unfoldr from HEAD:

Pipes.unfoldr Streaming.next        :: Stream (Of a) m r   -> Producer a m r
Streaming.unfoldr Pipes.next        :: Producer a m r      -> Stream (Of a) m r

Interoperation with iostreams is thus:

Streaming.reread IOStreams.read     :: InputStream a       -> Stream (Of a) IO ()
IOStreams.unfoldM Streaming.uncons  :: Stream (Of a) IO () -> IO (InputStream a)

for example. A simple exit to conduit would be, e.g.:

Conduit.unfoldM Streaming.uncons    :: Stream (Of a) m ()  -> Source m a
