# Wyes

type Wye a b c = Machine (Y a b) cSource

A `Machine`

that can read from two input stream in a non-deterministic manner.

type WyeT m a b c = MachineT m (Y a b) cSource

A `Machine`

that can read from two input stream in a non-deterministic manner with monadic side-effects.

addX :: Monad m => ProcessT m a b -> WyeT m b c d -> WyeT m a c dSource

Precompose a pipe onto the left input of a wye.

addY :: Monad m => ProcessT m b c -> WyeT m a c d -> WyeT m a b dSource

Precompose a pipe onto the right input of a tee.
