how to nest "for" segment in match segment

[prehonor]

view! {
    <div>
        <p>"status: " {status}</p>

        <button on:click=send_message disabled=move || !connected()>"Send"</button>
        <button on:click=open_connection disabled=connected>"Open"</button>
        <button on:click=close_connection disabled=move || !connected()>"Close"</button>
        {

          move || match message.get() {
                Some(result_info) => {
                    view! {
                        <p>"Receive message: " {format!("{:?}", result_info)}</p>
                        {result_info.result_info.trade_record.iter().enumerate().map(|(idx, _)| {
                                view! { <li>{idx}</li> }
                            }).collect_view()}
                    }.into_any()
                }
                _ =>
                    // 当 message.get() 为 None 时输出空的 <p></p>
                    view! { <p></p> }.into_any()
            }
        }
    </div>
}

I'm sorry, I don't understand the question.

Reading the code, though, this does not appear to be a valid Rust expression:

move || if message.get() {
                Some(result_info) => {
                    view! {
                        <p>"Receive message: " {format!("{:?}", result_info)}</p>
                        result_info.result_info.trade_record.iter().enumerate().map(|(idx, _)| {
                                view! { <li>{idx}</li> }
                            }).collect_view()
                    }.into_any()
                }
                else 
                    // 当 message.get() 为 None 时输出空的 <p></p>
                    view! { <p></p> }.into_any()
            }
        }

I see if message.get() { Some(result_info) => { which looks like a mix of an if expression and a match branch without a match

And then this is not a valid view macro, as Rust expressions need to be in brackets

view! {
                        <p>"Receive message: " {format!("{:?}", result_info)}</p>
                        result_info.result_info.trade_record.iter().enumerate().map(|(idx, _)| {
                                view! { <li>{idx}</li> }
                            }).collect_view()
                    }.into_any()

should be

view! {
                        <p>"Receive message: " {format!("{:?}", result_info)}</p>
                        {result_info.result_info.trade_record.iter().enumerate().map(|(idx, _)| {
                                view! { <li>{idx}</li> }
                            }).collect_view()}
                    }.into_any()

really sorry, I correct the question

[prehonor]

if I removed {result_info.result_info.trade_record.iter().enumerate().map(|(idx, _)| {
view! {

{idx}

}
}).collect_view()}, the code is passed

[prehonor]

view! {

"status: " {status}

        <button on:click=send_message disabled=move || !connected()>"Send"</button>
        <button on:click=open_connection disabled=connected>"Open"</button>
        <button on:click=close_connection disabled=move || !connected()>"Close"</button>

        {
          move || match message.get() {
                Some(result_info) =>
                    {view! {
                        // <p>"Receive message: " {format!("{:?}", result_info)}</p>
                        {
                            result_info.result_info.trade_record.iter().enumerate().map(|(idx, item)| {
                                item.iter().map(|item| {
                                    view! {

                                            {item.trade_moment_info.status}
                                            {item.trade_moment_info.avg_price}
                                            {item.trade_moment_info.left_vol}
                                            {item.trade_moment_info.data_index}

                                            {item.trade_moment_info.cur_money}
                                        </li>
                                    }
                                }).collect_view()

                            }).collect_view()
                        }

                    }.into_view()}

                _ =>
                    // 当 message.get() 为 None 时输出空的 <p></p>
                    {view! { <p></p> }.into_view()}
          }
        }
    </div>
}   the code  worked
