Description
I want to create a tls server with the code down below. config is a struct that stores the configuration, and it contains strings for client auth, cert and key paths. However, if these strings are invalid paths (or maybe just don't contain the "expected" content, I'm not sure), then warp::serve panics.

I tried this code:

        warp::serve(routes)
            .tls()
            .client_auth_required_path(config.client_ca_path)
            .cert_path(config.cert_path)
            .key_path(config.key_path)
            .run(socket)
            .await;

I expected to see this happen:
Some proper way of error handling. Can I work with a result somehow instead of it panicking?

Instead, this happened:

thread 'main' panicked at 'error binding to 0.0.0.0:3030: certificate parse error', /home/.../.cargo/registry/src/github.com-.../warp-0.3.5/src/server.rs:534:27

You can make use of try_bind_with_graceful_shutdown function that has been added recently.
