    robjtede on web-v4.0.0-beta.6


Code has been in production for a few months, too.
(or "transpile", if you prefer :) )

On a different note, my code just broke, possibly related to the release of actix-utils 3.0.0-beta.3.

   |                  ^^^^^^^ could not find `timeout` in `actix_utils`
I'm aware it's one of the risks of using beta versions, but I wonder if there's a solution at hand.
I ran a cargo clean && cargo update today, it built before that, not sure when the issue showed up, but my CI only broke one hour ago, so I assume it's very recent.
(which seems to be confirmed by the fact that actix-utils lost timeout only today)

you can pin versions that break stuff
eg: actix-utils = "=3.0.0-beta.2"
apologies for this, i'm working to release a bunch of new betas currently
No problem and thanks for the great work on actix-* :)
If you tell me I just need to take a break, I can do that, too :)
It's lunchtime anyway.
try not to run cargo update with actix-web betas
You want to stay on a combination works if possible. any update could break your project.
Yeah, I did that to try and understand why my CI broke down.
I suppose I should take the habit of pushing Cargo.lock to my git repo.
In that specific case, the following seems to work around the issue:
$ cargo update -p actix-utils --precise 3.0.0-beta.2
I have a general design question, possibly OT.
When there's some kind of panic! in a request, actix-web handles it gracefully, failing the request but keeping the server alive.
Now, my server also has a number of background tasks, e.g. it checks every few minutes for updates from another server.
What's the best design to handle panic! in such background task gracefully, without killing the server or the internal background task loop?
Right now, I have a loop that looks like
loop {
   if let Err(err) = tokio::task::spawn(...).await {
      warn!("Error in background task {:?}", err);
Is this a good design? Would actix agents somehow help me make it better/nicer?

Hi all! I'm fairly new to Rust and to actix-web, and I'm struggling with some sync/async stuff.. I'm trying to implement Stream, where in the stream I make some external HTTP requests. How do I call an async function (and wait for a result) in poll_next()?

Hi! Could it be that NamedFile from actix-files does not work together with Cors from actix-cors? It does not send me a CORs header, but my json endpoint does have CORs headers. Is this a bug?

Hi, I have a question which I could find an answer.
I want to create a route #[post("/get_something/{limit}/{skip}")]
I would make that limit and skip are optional so if you request /get_something it uses some predefined values from limit and skip but if I give values for limit or skip or both it will take those values

which is the best way of doing it, using a Json<> or Path()? or I must create 3 routes?
Thanks in advance for help


Why does tokio block actix? When I use tokio I can't connect to the server via websockets. the tokio code is time_now() function

actix code:

async fn main() -> std::io::Result<()> {
    let port = env::var("PORT")
        .unwrap_or_else(|_| "8081".to_string())
        .expect("PORT must be a number");
    println!("Server is working on {:?}", port);
    let chat_server = Lobby::default().start(); //create and spin up a lobby
        move || App::new()
        .bind(("", port))
        .expect("Can not bind to port")

tokio code:

pub async fn time_now() {

    let mut time: currentTime = currentTime {
        dayTime: "".to_string(),
        seconds: 0,
        minutes: 0,
        hours: 0,
        days: 0,
        shift: 0,

    let mut one_second = Duration::from_secs(1);
    actix::spawn(async move {
    loop {
        time.seconds += 1;
        if (time.seconds == 60) {time.minutes += 1; time.seconds = 0}
        if (time.minutes == 60) {time.hours += 1; time.minutes = 0}

Hey there I have an async function that is a loop running alongside my http server in an#[actix_web::main]. the problem is that this spawns multiple of these async loops instead of just one. I have a feeling that the actix run time creates multiple threads running the same main function? I'm wondering how I can get this to run as a single instance.

I think you need to use Tokio's time::delay_for function instead of thread::sleep

Hello web-dev friends, I need to clean up my AppState after the webserver has stopped. Is there a proper way to do that?

trying actix-web 4.0.0-beta.5, I'm adding a sqlx db pool as app data like this:


In an implementation of actix_web::FromRequest, I try to get the data back vialet pool = req.app_data::<actix_web::web::Data<sqlx::PgPool>>().unwrap().clone(); However, I see a None value being returned by app_data here. What am I doing wrong?

just an FYI if you're using any crates from the actix-extras repo hold off on upgrading actix-web until tomorrow

Did actix-web beta-6 change how JSON bodies are parsed? The last version I was using was beta-5. I'm getting this error without changing anything except updating actix-web:

the trait bound `fn(actix_web::web::Json<routes::api::search::SearchParameters>) -> impl std::future::Future {<routes::api::search::search_repositories as actix_web::dev::HttpServiceFactory>::register::search_repositories}: actix_web::dev::Handler<_, _>` is not satisfied

My function looks like this:

pub async fn search_repositories(
    query: web::Json<SearchParameters>,
) -> Result<HttpResponse, HttpResponse> {
    // ...
I'm trying to to compile with actix-web v4. Getting this error:
