route_manager

Used for adding, deleting, and querying routes, with support for asynchronous or synchronous monitoring of route changes.

Supported Platforms

Features:

1. Supporting Synchronous and Asynchronous API
2. Supports choosing between Tokio and async-io for asynchronous I/O operations.

Example:

Asynchronous API

use route_manager::{AsyncRouteManager, Route};
use std::time::Duration;
#[tokio::main]
pub async fn main() {
    let mut route_listener = AsyncRouteManager::listener().unwrap();
    tokio::spawn(async move {
        while let Ok(route) = route_listener.listen().await {
            println!("listen {route}");
        }
    });
    // Need to set up the correct gateway
    let route = Route::new("192.168.2.0".parse().unwrap(), 24).with_if_index(1);
    let mut manager = AsyncRouteManager::new().unwrap();
    let result = manager.add(&route).await;
    println!("route add {route} {result:?}");
    tokio::time::sleep(Duration::from_secs(1)).await;
    let result = manager.delete(&route).await;
    println!("route delete {route} {result:?}");
    tokio::time::sleep(Duration::from_secs(1)).await;
}

Synchronous API

use route_manager::{Route, RouteManager};
use std::thread;
use std::time::Duration;

pub fn main() {
    let mut route_listener = RouteManager::listener().unwrap();
    #[cfg(feature = "shutdown")]
    let shutdown_handle = route_listener.shutdown_handle().unwrap();
    thread::spawn(move || {
        while let Ok(route) = route_listener.listen() {
            println!("listen {route}");
        }
        println!("========= end =========");
    });
    // Need to set up the correct gateway
    let route = Route::new("192.168.2.0".parse().unwrap(), 24).with_if_index(1);
    let mut manager = RouteManager::new().unwrap();

    let result = manager.add(&route);
    println!("route add {route} {result:?}");
    thread::sleep(Duration::from_secs(1));
    let result = manager.delete(&route);
    println!("route delete {route} {result:?}");
    thread::sleep(Duration::from_secs(1));
    #[cfg(feature = "shutdown")]
    shutdown_handle.shutdown().unwrap();
    thread::sleep(Duration::from_secs(100));
}
