suspend fun BarcodeScanner.processSuspending(image: ImageProxy): Barcode? {
	return suspendCancelableCoroutine { continuation ->
		continuation.invokeOnCancelation {
			this.clear()
		}

		this.process(image)
			.addOnSuccessListener { barcodes ->
				val barcode = barcodes.someTransformation()
				continuation.resume(barcode)
			}
			.addOnFailure { throwable -> 
				continutaion.resumeWithException(throwable)
			}
	}
}

Would somebody mind looking at this if I do wrap a 3rd party callback library correctly? Its googles mlkit barcode scanner. Its my first time

Also, what is the best pragmatic name of providing a suspend function if the "native" is called process()? processSuspending() ? or some sort of await variant like awaitProcess()?
Also2, I don't need to apply dispatcher, since it provides callbacks, meaning it most likely has its own thread inside, right?

Looks alright, assuming that this.clear() is the correct way to clear all resources involved in the barcode scanner

[Erik]

I wouldn't call the function awaitX, because awaiting usually means using a Deferred<T> when working with coroutines.

[Erik]

If you can abstract all barcode scanner domain away, then you could simply name the suspending function process too, because nobody needs to know the original blocking function with the same name

[Erik]

Otherwise processSuspending is fine, or maybe processAsync if that's applicable

thanks!
