# 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!
