```rust
use iroh::protocol::{Protocol, ProtocolHandler, Router, RouterBuilder};
use std::io;

struct MyProtocolHandler;

impl ProtocolHandler for MyProtocolHandler {
    type Connection = io::Result<()>;

    async fn handle(&self, _connection: iroh::net::Connection) -> Self::Connection {
        // Handle the connection logic here
        Ok(())
    }
}

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let mut router = RouterBuilder::new();
    router.add(Protocol::new("router"), MyProtocolHandler);

    let router = router.build();
    let _ = router.spawn();

    // To accept connections, you would typically do something like this:
    // let mut builder = RouterBuilder::new();
    // builder.add(Protocol::new("my_protocol"), MyProtocolHandler);
    // let router = builder.build();
    // let listener = tokio::net::TcpListener::bind("127.0.0.1:12345").await?;
    // router.accept(Protocol::new("my_protocol"), listener).await?;

use iroh_net::endpoint::{Endpoint, EndpointConfig};
use iroh_net::protocol::ProtocolId;
use std::io;

#[tokio::main]
async fn main() -> io::Result<()> {
    // Configuration for the endpoint
    let config = EndpointConfig {
        // ... other configurations ...
        protocols: vec![ProtocolId::from("iroh-ping")],
    };

    // Create a new iroh endpoint
    let endpoint = Endpoint::new(config).await?;

    // Example: Connect to a peer (replace with actual peer address)
    // let peer_addr = "/ip4/127.0.0.1/tcp/12345/p2p/your_peer_id".parse().unwrap();
    // let mut conn = endpoint.connect(peer_addr, ProtocolId::from("iroh-ping")).await?;

    // Example: Accept incoming connections
    // tokio::spawn(async move {
    //     while let Some(conn) = endpoint.accept().await {
    //         tokio::spawn(handle_connection(conn));
    //     }
    // });

    // Placeholder for actual ping/pong logic
    println!("Endpoint created. Ready to handle iroh-ping protocol.");

    // Keep the endpoint running (e.g., with a signal handler or other logic)
    tokio::signal::ctrl_c().await?; 
    Ok(())
}

async fn handle_connection(mut conn: iroh_net::endpoint::Connection) -> io::Result<()> {
    println!("New connection established for iroh-ping.");
    // Implement ping/pong logic here
    // For example, read a ping message and send a pong response
    Ok(())
}

```

It binds an endpoint, spawns a gossip service, configures a router, subscribes to a topic, sends an initial 'AboutMe' message, and starts the `subscribe_loop` in a separate Tokio task for concurrent message handling.

```rust
use std::collections::HashMap;

use anyhow::Result;
use futures_lite::StreamExt;
use iroh::protocol::Router;
use iroh::{Endpoint, EndpointId};
use iroh_gossip::{
    api::{GossipReceiver, Event},
    net::Gossip,
    proto::TopicId,
};
use serde::{Deserialize, Serialize};

#[tokio::main]
async fn main() -> Result<()> {
    let endpoint = Endpoint::bind().await?;

    println!("> our endpoint id: {}", endpoint.id());
    let gossip = Gossip::builder().spawn(endpoint.clone());

    let router = Router::builder(endpoint.clone())
        .accept(iroh_gossip::ALPN, gossip.clone())
        .spawn();

    let id = TopicId::from_bytes(rand::random());
    let endpoint_ids = vec![];

    let (sender, receiver) = gossip.subscribe(id, endpoint_ids).await?.split();

    let message = Message::new(MessageBody::AboutMe {
        from: endpoint.id(),
        name: String::from("alice"),
    });
    sender.broadcast(message.to_vec().into()).await?;

    // subscribe and print loop
    tokio::spawn(subscribe_loop(receiver));

    router.shutdown().await?;

    Ok(())
}
```

```rust
let filename: PathBuf = filename.parse()?;
let abs_path = std::path::absolute(filename)?;
let ticket: BlobTicket = ticket.parse()?;

// For receiving files, we create a "downloader" that allows us to fetch files
// from other endpoints via iroh connections
let downloader = store.downloader(&endpoint);

println!("Starting download.");

downloader
    .download(ticket.hash(), Some(ticket.endpoint_addr().id))
    .await?;

println!("Finished download.");

println!("Copying to destination.");

store.blobs().export(ticket.hash(), abs_path).await?;

println!("Finished copying.");

// Gracefully shut down the endpoint
println!("Shutting down.");
endpoint.close().await;
```

--------------------------------

### Rust Argument Parsing with Tokio

Source: https://docs.iroh.computer/quickstart

This Rust code snippet shows how to parse command-line arguments within an asynchronous Tokio environment. It utilizes the `env::args().skip(1)` pattern to get arguments, excluding the program name itself. This is essential for configuring program behavior based on user input.

```rust
let mut args = env::args().skip(1);

```

--------------------------------

### Rust Example: Setting up Iroh Router

Source: https://docs.iroh.computer/connecting/gossip

This Rust code demonstrates how to set up an Iroh Router, which manages incoming connections and routes them to specific protocol handlers based on ALPN. It requires importing necessary components from the 'iroh' crate.

```rust
use iroh::protocol::{Router, Endpoint, EndpointId};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let endpoint = Endpoint::new().await?;
    let mut router = Router::new(endpoint.clone());

    // Add protocols to the router here
    // router.add_protocol(MyProtocol::new());

    let addr = endpoint.local_addr();
    println!("Listening on {:?}", addr);

    // Start the router
    let handle = tokio::spawn(async move {
        if let Err(e) = router.run().await {
            eprintln!("Router error: {:?}", e);
        }
    });

    // Keep the main task alive
    tokio::signal::ctrl_c().await?;
    println!("Shutting down...");

    // Clean shutdown (optional, depends on how you want to handle it)
    endpoint.close().await?;
    handle.abort();

    Ok(())
}

The router is then spawned to run in the background. The snippet also includes graceful shutdown logic triggered by a `Ctrl+C` signal.

```rust
// For sending files we build a router that accepts blobs connections &
// routes them
// to the blobs protocol.
let router = Router::builder(endpoint)
    .accept(iroh_blobs::ALPN, blobs)
    .spawn();

tokio::signal::ctrl_c().await?;

// Gracefully shut down the endpoint
