FRP.Reactive.Internal.Future

Time used in futures. The parameter t can be any Ord and Bounded type. Pure values have time minBound, while never-occurring futures have time 'maxBound.' type Time t = Max (AddBounds t)

newtype FutureG t a

Source

A future value of type a with time type t. Simply a time/value pair. Particularly useful with time types that have non-flat structure.

isNeverF :: (Bounded t, Eq t) => FutureG t t1 -> Bool

Source

inFuture :: ((Time t, a) -> (Time t', b)) -> FutureG t a -> FutureG t' b

Source

Apply a unary function within the FutureG representation.

inFuture2 :: ((Time t, a) -> (Time t', b) -> (Time t', c)) -> FutureG t a -> FutureG t' b -> FutureG t' c

Source

Apply a binary function within the FutureG representation.

runF :: Ord t => Sink t -> FutureG t (IO a) -> IO a

Source

Run a future in the current thread. Use the given time sink to sync time, i.e., to wait for an output time before performing the action.
