start :: Scheduler s => s -> (Subscriber s v -> SchedulerIO s ()) -> IO (Signal s v)

Starts a signal which executes action on s.

subscribeOn :: forall s v. Scheduler s => Signal s v -> s -> Signal s v

Returns a signal which subscribes to sig on scheduler sch.

deliverOn :: forall s t v. (Scheduler s, Scheduler t) => Signal s v -> s -> t -> Signal t v

Returns a signal which subscribes to sig on scheduler schA and delivers its events onto scheduler schB.

first :: forall s v. Scheduler s => Signal s v -> SchedulerIO s (Event v)

Subscribes to sig and synchronously waits for an event.

class Scheduler s

Represents a queue of IO actions which can be executed in FIFO order.

Instances

Scheduler BackgroundScheduler

Scheduler MainScheduler

data SchedulerIO s a

An IO computation that must be performed in a scheduler of type s.

Instances

Scheduler s => Monad (SchedulerIO s)

Functor (SchedulerIO s)

Scheduler s => Applicative (SchedulerIO s)

Scheduler s => MonadIO (SchedulerIO s)

Show v => Show (SchedulerIO BackgroundScheduler v)

Show v => Show (SchedulerIO MainScheduler v)

Unsafely executes a SchedulerIO action and shows the result. This is for DEBUGGING PURPOSES ONLY.

data Signal s v

A signal which will send values of type v on a scheduler of type s.

Instances

Scheduler s => Monad (Signal s)

Scheduler s => Functor (Signal s)

Scheduler s => MonadPlus (Signal s)

Scheduler s => Applicative (Signal s)

Scheduler s => MonadZip (Signal s)
