How to distinguish body errors and when a peer resets a connection with hyper::Error?

[beroal]

let conn = http1::Builder::new()
    .serve_connection(io, service_fn(move |req| service(cs.clone(), req)));
let watched_conn = graceful.watch(conn);
tokio::task::spawn(async move {
    if let Err(error) = watched_conn.await {
        dbg!(error);
    }
});

“Cargo.toml”:

hyper = { version = "1.6.0", features = ["server", "http1"] }

When a peer resets the connection, error is
hyper::Error(Io, Os { code: 104, kind: ConnectionReset, message: "Connection reset by peer" }). I suppose that error in the code above may be also an error returned by my implementation of the hyper::body::Body trait. I would like to distinguish body errors and when a peer resets a connection to log these error with different log levels.
However, all is_* methods of hyper::Error return false. Shouldn't one of the below methods

• is_body_write_aborted
• is_canceled
• is_closed

return true?
