Rust Derive Clone For a Specific Struct

Question

Note: I am using iced for the GUI TextInput and tokio for the networking TcpStream

I have the following:

#[derive(Debug, Clone)]
enum Message {
    Session(Result<Connection, ConnectionError>), //Async Handler
    SendMessage,
    Send(Result<Connection, ConnectionError>), //Async Handler
    InputChanged(String),
    Button(usize, ButtonMessage),
    None,
}

#[derive(Debug)]
enum ConnectionError {
    ConnectError(usize),
    SendError(usize),
}

#[derive(Debug)]
struct Connection {
    stream: TcpStream,
    loc: usize,
}

Problem is that my Connection struct contains a TcpStream that cannot be cloned (it wouldn't logistically make sense for it to be cloned anyway).

So I get the error...

So I removed the Clone

#[derive(Debug)]
enum Message {
    Session(Result<Connection, ConnectionError>), //Async Handler
    SendMessage,
    Send(Result<Connection, ConnectionError>), //Async Handler
    InputChanged(String),
    Button(usize, ButtonMessage),
    None,
}

and get the following errors:

>the trait bound `Message: Clone` is not satisfied

    |
516 |         let input = TextInput::new(

    |
26  | enum Message {
    | ------------ doesn't satisfy `Message: Clone`
...
522 |         .padding(15)
    |          ^^^^^^^ private field, not a method
    |
    = note: the method `padding` exists but the following trait bounds were not satisfied:
            `Message: Clone`

So I went to where the TextInput was located and removed the Clone as well.

#[derive(Debug)]
struct ClientAdminChatPaneContent {
    scroll: scrollable::State,
    input: text_input::State,
    input_value: String,
}


#[derive(Debug)]
enum ChatPaneMessage {
    InputChanged(String),
}

impl ClientAdminChatPaneContent {
    fn new() -> Self {
        ClientAdminChatPaneContent { 
            scroll: scrollable::State::new(),
            input: text_input::State::new(),
            input_value: String::from(""),
        }
    }

    fn update(&mut self, message: ChatPaneMessage) {
        match message {
            ChatPaneMessage::InputChanged(value) => {
                //println!("Input Changed: {}", value);
                self.input_value = value;
            }
        }
    }

    fn view(&mut self) -> Element<Message> {

        //Text Input
        let input = TextInput::new(
            &mut self.input,
            "Message to Client",
            &self.input_value,
            Message::InputChanged,
        )
        .padding(15)    
        .size(30)
        .on_submit(Message::SendMessage);
        
        let text_input_container:Container<Message> = Container::new(input)
            .width(Length::Fill)
            .height(Length::Units(80))
            .padding(10);

        let scroll = Scrollable::new(&mut self.scroll)
            .width(Length::Fill)
            .spacing(10)
            .align_items(Align::Start);

        let scroll_container:Container<Message> = Container::new(scroll)
            .width(Length::Fill)
            .height(Length::Fill)
            .padding(10);

        let mut content = Column::new()
            .spacing(5);

        content = content.push(scroll_container);
        content = content.push(text_input_container);

        Container::new(content)
            .width(Length::Fill)
            .height(Length::Fill)
            .padding(5)
            .center_y()
            .into()
    }

    fn clear_text(&mut self) {
        self.input_value = String::from("");
    }
}

And I get a new error:

>the trait bound `Message: Clone` is not satisfied
   --> src\main.rs:516:15

516 |         let input = TextInput::new(

As to why, I'm not sure why let input = TextInput::new( needs to implement Clone. But, assuming I need this struct to implement Clone, WITHOUT Message implementing Clone due to the TCP...

How do I get clone for a specific item, such as a TextInput without deriving it for every single item Or Is this an entirely different issue?
