Function reqwest_cross::fetch
source · pub fn fetch(
request: RequestBuilder,
on_done: impl 'static + Send + FnOnce(Result<Response, Error>)
)Expand description
Performs a HTTP requests and calls the given callback when done. NB: Needs to use a callback to prevent blocking on the thread that initiates the fetch. Note: Instead of calling get like in the example you can use post, put, etc. (See reqwest::Client).
Tokio example
let request = Client::new().get("http://httpbin.org/get");
let (tx, rx) = oneshot::channel();
fetch(request, move |result: Result<Response, Error>| {
tx.send(result.expect("Expecting Response not Error").status())
.expect("Receiver should still be available");
});
let status = rx.await?; //In actual use case code to prevent blocking use try_recv instead
assert_eq!(status, 200);
