Authentication in connection string

[FireMasterK]

It would be nice to be able to provide authentication in the connection string like the Rust client, so you do not need to manually log in or connect. This would be really helpful for me for use in Docker (because of networking changes) if the client can automatically reconnect and login without me having to.

The rust client on which this library is based on, does not have the credentials in the connect method, as shown in the example https://github.com/iggy-rs/iggy/blob/master/examples/src/getting-started/consumer/main.rs

Rather, the IggyClient only has it, but it is not used in this library.

I don't understand why the client "can automatically reconnect and login without you having to"....it's code, you write it once and if works you can run it multiple times. I don't understand the problem, do you mind elaborating the request?

Yes, but what prevents us from using it directly? It also uses the Tcp client behind the scenes. The IggyClientBuilder gives us an IggyClient instance upon building anyway. There's also IggyClientBuilder::from_connection_string which does the same thing as far as I can tell. I have been using this in my Rust application without any issues.

Let's say you have a hostname you want iggy to connect, and you initialize a client and connect like so:
You can initialize it like so:

    let iggy_client = IggyClient::from_connection_string(&iggy_address).unwrap();

    iggy_client.connect().await.unwrap();

vs

Details

    let iggy_client = IggyClientBuilder::new()
        .with_tcp()
        .with_server_address(iggy_address)
        .build()
        .unwrap();

    iggy_client.connect().await.unwrap();

    iggy_client.login_user("iggy", "iggy").await.unwrap();

When you connect this way, the client seems more fault tolerant from my observation in my Rust app. Previously, I used to get a Pipe broken error, in case my iggy server's IP changes (hostname remains the same).

This error caused me to need to restart my application every time this happened. I'm not sure but maybe this could be fixed at runtime by calling connect and login_user again, but would be really inconvenient since I would need to handle this error everywhere I use iggy.

If the server IP changes continuously, this is an edge case and also a problem for many other libraries in general. I think you need to first check your configuration/topology
