Type Alias StartupMessageCallback 

pub type StartupMessageCallback = Box<dyn Fn(ResponseMessage) + Send + Sync>;

Callback for handling unsolicited messages during connection setup.

When TWS sends messages like OpenOrder or OrderStatus during the connection handshake, this callback is invoked to allow the application to process them instead of discarding them.

Example

use ibapi::{Client, StartupMessageCallback};
use ibapi::messages::IncomingMessages;
use std::sync::{Arc, Mutex};

#[tokio::main]
async fn main() {
    let orders = Arc::new(Mutex::new(Vec::new()));
    let orders_clone = orders.clone();

    let callback: StartupMessageCallback = Box::new(move |msg| {
        match msg.message_type() {
            IncomingMessages::OpenOrder | IncomingMessages::OrderStatus => {
                orders_clone.lock().unwrap().push(msg);
            }
            _ => {}
        }
    });

    let client = Client::connect_with_callback("127.0.0.1:4002", 100, Some(callback))
        .await
        .expect("connection failed");

    println!("Received {} startup orders", orders.lock().unwrap().len());
}
