# Building Web Servers in Rust

Rust has become a popular choice for building web servers due to its performance and safety guarantees.

## Why Rust for Web Development?

1. **Memory Safety**: No null pointer exceptions or data races
2. **Performance**: Comparable to C/C++
3. **Concurrency**: Fearless concurrency with async/await
4. **Type System**: Catch errors at compile time

## Popular Frameworks

### Axum

Axum is a modern web framework built on top of Tokio. It provides:

- Type-safe routing
- Extractors for parsing requests
- Middleware support
- Great ergonomics

### Actix Web

Actix Web is a powerful, pragmatic framework that:

- Uses the actor model
- Provides excellent performance
- Has a mature ecosystem

### Rocket

Rocket focuses on:

- Developer ergonomics
- Type-safe routing
- Easy to learn

## Example Server

```rust
use axum::{routing::get, Router};

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(|| async { "Hello, World!" }));

    let listener = tokio::net::TcpListener::bind("127.0.0.1:3000")
        .await
        .unwrap();

    axum::serve(listener, app).await.unwrap();
}
```

This is just the beginning of what you can build with Rust!
