Struct ApplicationHandle 

pub struct ApplicationHandle { /* private fields */ }

Handle for a registered application bridge

This handle manages the lifetime of both the C++ RustApplicationBridge and the Rust FixApplication trait object. The bridge receives callbacks from the FIX engine and forwards them to the trait methods.

Example

use fixantenna_bindings::{ApplicationHandle, FixApplication, FixMessage, Session};

struct MyApp;

impl FixApplication for MyApp {
    fn process(&mut self, msg: &FixMessage, _session: &Session) -> bool {
        println!("Received message");
        true
    }
}

// Create handle with custom application
let handle = ApplicationHandle::with_app(MyApp);

// Or use default (accepts all messages)
let handle = ApplicationHandle::new();

Implementations

impl ApplicationHandle

pub fn with_app<T: FixApplication>(app: T) -> Self

Create a new ApplicationHandle with a custom FixApplication

This creates a C++ RustApplicationBridge that will forward callbacks to the provided FixApplication trait object.

Arguments

• app - Your implementation of FixApplication

Example

use fixantenna_bindings::{ApplicationHandle, FixApplication, FixMessage, Session, LogonEvent, SessionIdWrapper, logon_action};

struct EchoApp;

impl FixApplication for EchoApp {
    fn process(&mut self, msg: &FixMessage, session: &Session) -> bool {
        session.put(msg).is_ok()
    }
    fn on_logon(&mut self, event: &mut LogonEvent, _sid: &SessionIdWrapper) {
        event.set_logon_action(logon_action::ACCEPT_WITH_CONFIRM_LOGON);
    }
}

let handle = ApplicationHandle::with_app(EchoApp);

pub fn new() -> Self

Create a new ApplicationHandle with default behavior

Uses the default FixApplication implementation which:

• Accepts all incoming messages (returns true from process)
• Accepts all logons with confirmation
• Does not reconnect on logout
• Allows all resends

pub fn bridge_ptr(&self) -> usize

Get the C++ bridge pointer
