问题 I have an actix endpoint, and I need to do a synchronous http client fetch to get some results, and return some data. My endpoints cannot use async , so I can't use any .await methods. I've tried using reqwests blocking client in my endpoint like so: { ... let res = reqwest::blocking::get(&fetch_url)? .json::<MyResp>()?; ... But it gives me the error: thread 'main' panicked at 'Cannot start a runtime from within a runtime. This happens because a function (like `block_on`) attempted to block

问题 I started working on my first more ambitious Rust project, and struggle with something I did not come across in any of the resources and tutorials I used for learning. The title of the question captures the abstract problem, but for the examples I'll use the concrete examples I am fighting with. For my project, I need to interface with different third-party services, and I decided to use the actix framework as an abstraction for the different actors in my domain. The framework defines the

问题 I'm building a web api service with rust and actix. I want to test a route and check if the received response body is what i expect. But I'm strugeling with converting the received body (ResponseBody) into a Json/Bson. The called route actually returns application/json. Thanks for your help. let mut app = test::init_service(App::new() .data(AppState { database: db.clone() }) .route("/recipes/{id}", web::post().to(add_one_recipe))).await; let payload = create_one_recipe().as_document().unwrap(

问题 I want to use the async function to parse the inbound stream progressively, but actix-web requires impl Future<Item = HttpResponse, Error = Error> as the return value. How can I convert the future returned by async function to what actix-web requires? I'm using Rust 1.39 nightly and actix-web 1.0.7. http_srv.rs : use futures::compat::Stream01CompatExt; use futures::future::{FutureExt, TryFutureExt}; use futures::stream::TryStreamExt; use futures01::future::Future; use futures01::stream:
