feature-request/discuss: is there a better way to handle HTTP error codes in the async flavor?

[sxlijin]

In my own use case, I currently find myself doing some variant of this a lot:

let resp = reqwest_client.post(...).send().await;

if resp.status().is_success() {
  let json: MyReturnType = resp.json().await;
  Ok(do_something_with(json))
} else {
  let body = resp.text().await;
  Err(format!("Uh-oh, request failed: {} {}", resp.status(), body))
}

Has there been any discussion of returning a Result<impl Future<Output = serde_json::Value>, reqwest::Error> where the Ok consumes the .json() and the Err consumes the .body()? Am I missing something blindingly obvious here? Are there 3rd-party crates above reqwest that handle this?

I do recognize that with the async client, .send().await must precede the .json().await/.text().await because the status code is available in the response bytes coming across the wire before the remainder of the response is.

@seanmonstar do you have any thoughts on this? Am I the first person to bring this up?
