Logging IP addresses of login attemts

[DarkWingMcQuack]

I have a service running with tide and basic auth and in the last few days it seems that some bots are trying to bruteforce the login credentials.
To analyse and avoid this i would like to log the login attemts and ip addresses of the peer which attemted the login.
Is this possible with tide-http-auth?
I wasnt able to do this.

I tried this:

if req.ext::<User>().is_none() {
  let sender = req.peer_addr().unwrap_or("<UNKNOWN>");
  warn!("{} tried to authenticate with wrong credentials!!", sender);

  let mut response: tide::Response = "fuck off!!!".to_string().into();
  response.set_status(tide::http::StatusCode::Unauthorized);
  return Ok(response);
}

But this only triggers if there is no authentication header at all and not if the credentials are wrong.
