FRP.Rhine.Type

Description

The type of a complete Rhine program: A signal network together with a matching clock value.

Synopsis

data Rhine m cl a b = Rhine {
- sn :: SN m cl a b
- clock :: cl
}
eraseClock :: (Monad m, Clock m cl, GetClockProxy cl) => Rhine m cl a b -> m (MSF m a (Maybe b))

Documentation

data Rhine m cl a b Source #

A Rhine consists of a SN together with a clock of matching type cl.

It is a reactive program, possibly with open inputs and outputs. If the input and output types a and b are both (), that is, the Rhine is "closed", then it is a standalone reactive program that can be run with the function flow.

Otherwise, one can start the clock and the signal network jointly as a monadic stream function, using eraseClock.

eraseClock :: (Monad m, Clock m cl, GetClockProxy cl) => Rhine m cl a b -> m (MSF m a (Maybe b)) Source #

Start the clock and the signal network, effectively hiding the clock type from the outside.

Since the caller will not know when the clock In cl ticks, the input a has to be given at all times, even those when it doesn't tick.
