Getting rather odd error when doing foreign 'sync' requests using reqwest crate in any handler.

Maybe this issue is related to #307?

Tried to use a custom executor for Gotham server but got the same result.

Maybe someone has had a similar error? Can't find much docs about it or true origin to debug further.

To use reqwest in a future context, use their async client.
Here is their example from https://github.com/seanmonstar/reqwest/blob/master/examples/async.rs translated into a gotham handler:

pub fn say_hello(state: State) -> Box<HandlerFuture> {
    let f = Client::new()
        .get("https://hyper.rs")
        .send()
        .and_then(|mut res| {
            println!("{}", res.status());

            let body = mem::replace(res.body_mut(), Decoder::empty());
            body.concat2()
        })
        .map_err(|err| println!("request error: {}", err))
        .map(|body| {
            let mut body = Cursor::new(body);
            let _ = io::copy(&mut body, &mut io::stdout()).map_err(|err| {
                println!("stdout error: {}", err);
            });
        });

    Box::new(f.then(move |_result| {
        let res = create_response(&state, StatusCode::OK, mime::TEXT_PLAIN, HELLO_WORLD);
        Ok((state, res))
    }))
}
