Description

Concurrent ML library.

This library provides first-class synchronous events in the style of CML (http://cml.cs.uchicago.edu/). This library implements a simplified CML interface, eliding the withNack combinator.

Synopsis
type Evt a = IO (Evt (IO a))
alwaysEvt :: a -> Evt a
wrapEvt :: Evt a -> (a -> IO b) -> Evt b
guardEvt :: IO (Evt a) -> Evt a
neverEvt :: Evt a
chooseEvt :: Evt a -> Evt a -> Evt a
sync :: Evt a -> IO a
type SChan a = SChan a
newSChan :: IO (SChan a)
sendEvt :: SChan a -> a -> Evt ()
recvEvt :: SChan a -> Evt a
timeOutEvt :: Int -> Evt ()
TxEvent type
type Evt a = IO (Evt (IO a))
