Exploring Rust for Backend Development

Why Rust for Backend?

Rust offers memory safety without garbage collection, making it perfect for high-performance backend services.

Getting Started with Axum

Axum is a modern, ergonomic web framework for Rust that leverages the power of the ecosystem.

use axum::{
    routing::{get, post},
    http::StatusCode,
    Json, Router,
};

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(root))
        .route("/users", post(create_user));

    axum::Server::bind(&"0.0.0.0:3000".parse().unwrap())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

async fn root() -> &'static str {
    "Hello, World!"
}

Performance Benefits

Rust applications typically show:

• 50-80% lower memory usage
• 2-5x better throughput
• Near-zero latency variance

Developer Experience

While the learning curve is steep, the benefits include:

• Compile-time error prevention
• Excellent tooling (cargo, clippy, rustfmt)
• Strong community and ecosystem

Conclusion

Rust is becoming a compelling choice for backend development, especially for performance-critical applications.
