There is no way to pass data to the new Server connection service in Hyper 1 #3463
Description
Version
Hyper 1
Description
In Hyper 0.14, you could create a service that passed data to the connection service. This example in the old documentation explained how:
use std::convert::Infallible;
use std::net::SocketAddr;
use hyper::{Body, Request, Response, Server};
use hyper::service::{make_service_fn, service_fn};
use hyper::server::conn::AddrStream;
#[derive(Clone)]
struct AppContext {
// Whatever data your application needs can go here
}
async fn handle(
context: AppContext,
addr: SocketAddr,
req: Request<Body>
) -> Result<Response<Body>, Infallible> {
Ok(Response::new(Body::from("Hello World")))
}
#[tokio::main]
async fn main() {
let context = AppContext {
// ...
};
// A `MakeService` that produces a `Service` to handle each connection.
let make_service = make_service_fn(move |conn: &AddrStream| {
// We have to clone the context to share it with each invocation of
// `make_service`. If your data doesn't implement `Clone` consider using
// an `std::sync::Arc`.
let context = context.clone();
// You can grab the address of the incoming connection like so.
let addr = conn.remote_addr();
// Create a `Service` for responding to the request.
let service = service_fn(move |req| {
handle(context.clone(), addr, req)
});
// Return the service to hyper.
async move { Ok::<_, Infallible>(service) }
});
// Run the server like above...
let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
let server = Server::bind(&addr).serve(make_service);
if let Err(e) = server.await {
eprintln!("server error: {}", e);
}It's the last example in the old documentation: https://docs.rs/hyper/0.14.27/hyper/server/index.html#examples
This seems impossible to achieve now because serve_connection takes a service that receives Request<ReqBody>.
I expected to find an example or explanation on how to accomplish this with the new stable version, but it seems just gone.
How can I accomplish this in Hyper 1?
