asynchronous

问题 My rust program is managing memory for a 2d html canvas context, and I'm trying to hit ~60fps. I can calculate the delta between each frame easily, and it turns out to be roughly ~5ms. I'm unclear on how to put my Rust webassembly program to sleep for the remaining 11ms. One option would be to have JavaScript call into Rust on every requestAnimationFrame and use that as the driver, but I'm curious to keep it all in Rust if possible. I'm effectively looking for the Rust equivalent of

问题 I want to extend my experience with the .NET framework and want to build a client/server application. Actually, the client/server is a small Point Of Sale system but first, I want to focus on the communication between server and client. In the future, I want to make it a WPF application but for now, I simply started with a console application. 2 functionalities: client(s) receive(s) a dataset and every 15/30min an update with changed prices/new products (So the code will be in a Async method

问题 I have a Test plan with several HTTP request I want to reach a certain TPS. Some request takes more than a few seconds, and I want to execute them in asynchronous way so I'll continue executing other request while waiting for response asynchronously (later to be checked) Better yet (general case), I would like to have a time limit of 3 seconds wait, and if 3 seconds past to continue to next request Is there a way to submit such scenario in JMeter? or other tool executing JMeter as Taurus or

问题 I'm new to Dart and therefore having trouble with asynchronous programming. I'm trying to loop through a list of elements (let's call them ingredients for now) and query the database for recipes which contain the ingredient. To achieve this, I have a list 'ingredientsSelectedList' and pass it over to a future which is supposed to query the Firestore Database and add the result to the 'possibleRecipes' List. The problem is, that I can't figure out how to 'await' the for loop to finish, before

问题 I have been trying to create a function that is similar to http.get(...) but not doing any http. Basically what I have done is that I defined a function async myFunc(): Observable<string> { var myObservable: Observable<string>; //..... // the rest of the function's code comes here // ... return myObservable; } But I always get an error that it is not compatible with ES5/ES3 and should return a Promise object? But I am wondering how it became possible with Angular 5's http.get function? Where

问题 I am using react redux, and trying to call rest-api, and return the data. The fetch is asynchronous, and I need to return value only when the fetch is finished. I tried the following, but this didn't work properly (there is no 'wait' on the line that is with asterisks) - What shall I do? Code: ----- var _getData = function() { return new Promise((resolve, reject) => { let options = { method: 'GET', } let _url = "my web return json"; fetch(_url, options) .then(response => response.json(). then

问题 I have an Asp.Net 4.5 webforms application with a report which I'm trying to run using async await. Here is an example of the code I'm using: protected async void btnReport_Click(object sender, EventArgs e) { lblStatus.Text = "Working!"; await LongRunningTask(); } private async Task LongRunningTask() { await Task.Delay(5000); lblStatus.Text = "Done!"; } Everything I've read seems to suggest that the first method should complete immediately and update the label but this is not the case. The

问题 I use Springboot2 and Java 8. I have been banging my head to the wall on this one, hours spent but no clue what the problem is. I try to make two independent external calls via CompletableFuture. once both they complete I want to combine their results and return to the user. On the logs I see first request is successfull but I get HTTP 503 error on the second request just on the line "restTemplate.postForEntity(..)" Note: I do NOT use any Spring based @Async (or any Spring non blocking code)
