Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.

Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():

I was once in your shoe before and came across this Open source library called particle animations.

I would NOT recommend using the library itself since it's deprecated. But I would recommend referring to its source code to get an idea of how to use CAEmitterLayer and CAEmitterCell to make the looks of a Fire!

As you could see from its readme, it has direct examples of Fire. It also states that even Apple and Facebook uses CAEmitterLayer and CAEmitterCell to produce the effect of a fire.

Feel free to ask for more questions.

fromCallable doesn't shield you from blocking computation inside the Callable, which your example demonstrates.

The primary mean of cancellation in Reactive Streams is the cancel() signal propagated from downstream via the Subscription.

Even with that, the fundamental requirement of avoiding blocking code inside reactive code still holds, because if the operators are simple enough (ie. synchronous), a blocking step could even prevent the propagation of the cancel() signal...

A way to adapt non-reactive code while still getting notified about cancellation is Mono.create: it exposes a MonoSink (via a Consumer) which can be used to push elements to downstream, and at the same time it has a onCancel handler.

You would need to rewrite your code to eg. check an AtomicBoolean on each iteration of the loop, and have that AtomicBoolean flipped in the sink's onCancel handler:

A regular expression can check if the respCode matches v###, extract the numbers, then call .instant with those numbers.

You've made a mess of things by incorrectly installing the module. Specifically, you didn't install the dependencies.

Ideally, you should use the package manager that provided perl itself. But they don't provide every module. So you'd use the non-package manager approach:

I believe this comes close to what you were after.

Two adjustments:

1. changed widget positioning to absolute -- transforming with position: relative was repositioning the widgets in an inconsistent manner.

2. had to adjust the translate -- I'm no expert with this library but it looks like the nativeElement transform properties are set relative to the position of the drawer option the user selects (the NOTE vs COLUMN options in your example). If you add more options you might have to adjust x,y for each depending on where the option is in the drawer space.

Hope this helps and cheers!

You can convert the List to a Map of its index to the list value using the List.asMap() method.

The map uses the indices of this list as keys and the corresponding objects as values.

Change this part of your code:

If the memory pool was allocated as a single object (like result of a single malloc() or a global array) then pointer arithmetics can be safely used.

The main issue is that useEffect hook callbacks can't be async functions as these implicitly return a Promise which would, by design, be interpreted as an useEffect hook cleanup function. This won't work.

After looking at your code for a bit it looks like getting and setting the data state is independent of the firebase subscription. You can minify just the asynchronous logic into an async function to get and set the user data and invoke that, and access the firebase collection as per normal.

Use a React ref to hold on to the unsubscribe callback.

I think the following implementation should get you very close to what you are looking for. (Disclaimer: I've not tested this code but I think it should work)
