Create an external observer from a function and subscribe it to this observable.

Note: since you won't have a reference to the observer, you will need to call Subscription.kill() to unsubscribe

value
is passed by name, so it will be evaluated whenever the Observable fires.
Use it to sample mutable values (e.g. myInput.ref.value in Laminar).

Add a noop observer to this signal to ensure that it's started. This lets you access .now and .tryNow on the resulting StrictSignal.
Add a noop observer to this signal to ensure that it's started. This lets you access .now and .tryNow on the resulting StrictSignal.
You can use myStream.toWeakSignal.observe.tryNow()
to read the last emitted
value from event streams just as well.

Set the display name for this instance (observable or observer).
Set the display name for this instance (observable or observer).
- This method modifies the instance and returns
this
. It does not create a new instance. - New name you set will override the previous name, if any. This might change in the future. For the sake of sanity, don't call this more than once for the same instance.
- If display name is set, toString will output it instead of the standard type@hashcode string

Note: Observer can be added more than once to an Observable. If so, it will observe each event as many times as it was added.
