You have included fetching function in the component as it is, so it fires every time component being rendered. You better to include fetching data in useEffect hook just like this:

There 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"

The 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 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.)

How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

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.

Rust futures / async - await strange behavior

Asked 2021-Jun-15 at 20:06

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 20:06

You are not measuring the elapsed time correctly:

total_send_time measures the duration of the spawn() 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 in time, as measured by start.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 the std::thread::sleep()
Last but not least, your time_to_sleep calculation is completely incorrect, because of the issue mentioned in point 1.
