CustomSource

Create a new observable that listens to this one and has a debugger attached.

Use the resulting observable in place of the original observable in your code. See docs for details.

There are more convenient methods available implicitly from DebuggableObservable and DebuggableSignal, such as debugLog(), debugSpyEvents(), etc.

This is the method that subclasses override to preserve the user's ability to set custom display names.

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).

See also: mapToStrict

value is evaluated strictly, only once, when this method is called.

Convert this to an observable that emits Failure(err) instead of erroring

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

Override defaultDisplayName instead of this, if you need to.

Convert this observable to a signal of Option[A]. If it is a stream, set initial value to None.

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.

Note: This is enforced to be a Set outside of the type system #performance
