,-----------------------------. | StumbleUpon's Async Library | `-----------------------------'. This Java library provides some useful building blocks to build high-performance multi-threaded asynchronous applications in Java. Its implementation was inspired by Twisted's asynchronous library (twisted.internet.defer). Deferred allows you to easily build asynchronous processing chains that must trigger when an asynchronous event (I/O, RPC and whatnot) completes. It can be used extensively to build an asynchronous API in a multi-threaded server or client library.

I'm trying to understand how parallelization works in Durable Function. I have a durable function with the following code:
...ANSWER
Answered 2021-Jun-10 at 08:44There are two approaches that are possible. The first is to use a suborchestrator for each job so that each suborchestrator handles just a specific job. Here is the docs for this approach https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-sub-orchestrations?tabs=csharp Example from docs seem to be alike to yours.
The other is to use ContinueWith so that each job has its own "chain"

ANSWER
Answered 2021-Jun-16 at 00:46The issue you are having has nothing to do with templates. You cannot invoke std::async() on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.
Here's an example:

I've ran into problem getting UI lags when this line is running:
...ANSWER
Answered 2021-Jun-16 at 00:29I don't believe you can use SharedPreferences within an Isolate without support for MethodChannel / accessing platform-specific underlying OS frameworks on iOS / Android.
You would need to use FlutterIsolate or a similar package to provide that support.
chunhunghan has a good answer detailing this.
Alternatively, you could run the crypt.generateKeys() by itself in your Isolate.spawn() call and use the results after in a separate method accessing SharedPreferences. (Assuming that crypt package is also not relying on platform-specific code.)
QUESTION
I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION
I am new to rust and I was reading up on using futures and async / await in rust, and built a simple tcp server using it. I then decided to write a quick benchmark, by sending requests to the server at a constant rate, but I am having some strange issues.
The below code should send a request every 0.001 seconds, and it does, except the program reports strange run times. This is the output:
...ANSWER
Answered 2021-Jun-15 at 20:06You are not measuring the elapsed time correctly:
total_send_timemeasures the duration of thespawn()call, but as the actual task is executed asynchronously,start_in.elapsed()does not give you any information about how much time the task actually takes.The
ran intime, as measured bystart.elapsed()is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in thestd::thread::sleep()Last but not least, your
time_to_sleepcalculation is completely incorrect, because of the issue mentioned in point 1.

Install async
You can use async like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the async component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
