Event and signal changes loggers.
Loggers are the output interface of the reactive system. They allow external entities to observe event occurences and signal changes.
Observations
val const : 'a -> 'a obsconst v never changes and always observes v.
app f v is the observation that result from applying the changes of f to the ones of v.
Loggers
create ~now o is a logger that observes changes to o. If now is true (default) logs at least one observation before the call returns.
val force : t -> unitforce l observes l even if nothing changed.
val destroy : t -> unitdestroy l destroys log l this ensure that l's does not observe any change again. The underlying observed events or signals also stop updating, unless they are observed by another logger.
val hold : t -> unithold l holds logger l to ensure it does not get garbage collected.
val may_hold : t option -> unitmay_hold l holds logger Some l to ensure it does not get garbage collected. Does nothing on None.
