Module S.BoolSource

Sourceval zero : bool React.signal
Sourceval one : bool React.signal
Sourceval not : bool React.signal -> bool React.signal
Sourceval (&&) : bool React.signal -> bool React.signal -> bool React.signal
Sourceval (||) : bool React.signal -> bool React.signal -> bool React.signal
Sourceval edge : bool React.signal -> bool React.event

edge s is changes s.

Sourceval rise : bool React.signal -> unit React.event

rise s is E.fmap (fun b -> if b then Some () else None) (edge s).

Sourceval fall : bool React.signal -> unit React.event

fall s is E.fmap (fun b -> if b then None else Some ()) (edge s).

Sourceval flip : bool -> 'a React.event -> bool React.signal

flip b e is a signal whose boolean value flips each time e occurs. b is the initial signal value.

  • [flip b e]0 = not b if [e]0 = Some _
  • [flip b e]t = b if [e]<=t = None
  • [flip b e]t = not [flip b e]t-dt if [e]t = Some _
