Description

This modules exposes a monadic interface of ZMQ4. Actions run inside a ZMQ monad and Sockets are guaranteed not to leak outside their corresponding runZMQ scope. Running ZMQ computations asynchronously is directly supported through async.

Type Definitions

data ZMQ z a Source #

The ZMQ monad is modeled after ST and encapsulates a Context. It uses the uninstantiated type variable z to distinguish different invoctions of runZMQ and to prevent unintented use of Sockets outside their scope. Cf. the paper of John Launchbury and Simon Peyton Jones Lazy Functional State Threads.

General Operations

version :: ZMQ z (Int, Int, Int) Source #

runZMQ :: MonadIO m => (forall z. ZMQ z a) -> m a Source #

Return the value computed by the given ZMQ monad. Rank-2 polymorphism is used to prevent leaking of z. An invocation of runZMQ will internally create a Context and all actions are executed relative to this context. On finish the context will be disposed, but see async.

async :: ZMQ z a -> ZMQ z (Async a) Source #

Run the given ZMQ computation asynchronously, i.e. this function runs the computation in a new thread using async. N.B. reference counting is used to prolong the lifetime of the Context encapsulated in ZMQ as necessary, e.g.:

runZMQ $ do
    s <- socket Pair
    async $ do
        liftIO (threadDelay 10000000)
        identity s >>= liftIO . print

Here, runZMQ will finish before the code section in async, but due to reference counting, the Context will only be disposed after async finishes as well.
