Tees
type Tee a b c = Machine (T a b) c Source
A Machine
that can read from two input stream in a deterministic manner.
type TeeT m a b c = MachineT m (T a b) c Source
A Machine
that can read from two input stream in a deterministic manner with monadic side-effects.
tee :: Monad m => ProcessT m a a' -> ProcessT m b b' -> TeeT m a' b' c -> TeeT m a b c Source
Compose a pair of pipes onto the front of a Tee.
addL :: Monad m => ProcessT m a b -> TeeT m b c d -> TeeT m a c d Source
Precompose a pipe onto the left input of a tee.
addR :: Monad m => ProcessT m b c -> TeeT m a c d -> TeeT m a b d Source
Precompose a pipe onto the right input of a tee.
capL :: Monad m => SourceT m a -> TeeT m a b c -> ProcessT m b c Source
Tie off one input of a tee by connecting it to a known source.
