doEvent :: Scheduler s => Signal s v -> (Event v -> SchedulerIO s ()) -> Signal s vSource
Runs a side-effecting action whenever the signal sends an event.
doNext :: Scheduler s => Signal s v -> (v -> SchedulerIO s ()) -> Signal s vSource
Runs a side-effecting action whenever the signal sends a value.
doError :: Scheduler s => Signal s v -> (IOException -> SchedulerIO s ()) -> Signal s vSource
Runs a side-effecting action whenever the signal sends an error.
doCompleted :: Scheduler s => Signal s v -> SchedulerIO s () -> Signal s vSource
Runs a side-effecting action when the signal completes.
finally :: Scheduler s => Signal s v -> SchedulerIO s () -> Signal s vSource
Runs a side-effecting action when the signal completes or errors.
materialize :: Scheduler s => Signal s v -> Signal s (Event v)Source
Brings every signal event into the monad, as a NextEvent containing the event itself.
dematerialize :: Scheduler s => Signal s (Event v) -> Signal s vSource
The inverse of materialize.
fromFoldable :: (Foldable t, Scheduler s) => t v -> Signal s vSource
Turns any Foldable into a signal.
filter :: Scheduler s => Signal s v -> (v -> Bool) -> Signal s vSource
Filters the values of a signal according to a predicate.
take :: (Integral n, Scheduler s) => Signal s v -> n -> Signal s vSource
Returns a signal of the first n elements.
drop :: (Integral n, Scheduler s) => Signal s v -> n -> Signal s vSource
Returns a signal without the first n elements.
switch :: forall s v. Scheduler s => Signal s (Signal s v) -> Signal s vSource
Returns a signal that sends the values from the most recently sent signal.
combine :: forall a b s. Scheduler s => Signal s a -> Signal s b -> Signal s (a, b)Source
Combines the latest values sent by both signals.
A signal which will send values of type v on a scheduler of type s.
