New framework for Rust gains popularity in 2024

New framework for Rust gains popularity: what developers need to know

The Rust language ecosystem continues to actively develop, and 2024 has been a real breakthrough for one of its new web frameworks. We are talking about the Axum project — an asynchronous framework for building web applications that has shown explosive growth in popularity over the past six months. According to GitHub data and Stack Overflow surveys, Axum has outpaced veterans like Actix-web and Rocket in adoption rates.

Why Axum?

Axum is built on the Tokio and Tower libraries, ensuring maximum performance and compatibility with existing Rust projects. Here are the key reasons for its rapid growth:

• Simplicity and ergonomics: The framework uses Rust's powerful type system to validate routes at compile time.
• Full compatibility with Tower: Developers can easily plug in middleware from the vast Tower ecosystem (logging, compression, request limits).
• Excellent documentation: Code examples cover 90% of typical tasks — from REST API to WebSocket.
• Support for async/await: Native asynchrony without unnecessary macros.

Example of a minimal server on Axum

To appreciate the simplicity, just look at the code for a basic HTTP server:

use axum::{Router, routing::get, response::Html};

#[tokio::main]async fn main() {    let app = Router::new()        .route("/", get(|| async { Html("<h1>Hello, world!</h1>") }));

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

Just 10 lines of code — and you have a working web server with performance comparable to C++.

Comparison with competitors

For clarity, here are the main differences between Axum and other popular Rust frameworks:

• Actix-web: Faster, but more complex in type configuration. Axum wins in code readability.
• Rocket: Convenient for prototyping, but requires a nightly compiler version. Axum is stable on stable Rust.
• Warp: Flexible, but with a steep learning curve. Axum offers a flatter curve.

Forecasts and future

Analysts note that Axum's popularity is directly linked to the trend towards microservices and WebAssembly. Since Rust is increasingly used in high-load systems (for example, in cloud providers and blockchain projects), a simple and safe framework is becoming the de facto standard.

Already, large companies such as Discord and Cloudflare are partially migrating their Rust services to Axum. For Python developers learning Rust, this framework is the best entry point thanks to the familiar async/await syntax and abundance of ready-made examples.
