axum

axum is a web application framework that focuses on ergonomics and modularity.

More information about this crate can be found in the crate documentation.

Goals

• Ease of use. Building web apps in Rust should be as easy as async fn handle(Request) -> Response.
• Solid foundation. axum is built on top of tower and hyper and makes it easy to plug in any middleware from the tower and tower-http ecosystem. This improves modularity since axum doesn't have its own custom middleware system.
• Focus on routing, extracting data from requests, and building responses. tower middleware can handle the rest.
• Macro free core. Macro frameworks have their place but axum focuses on providing a core that is macro free.

Usage example

use axum::prelude::*;
use hyper::Server;
use std::net::SocketAddr;

#[tokio::main]
async fn main() {
    // build our application with a single route
    let app = route("/", get(|| async { "Hello, World!" }));

    // run it with hyper on localhost:3000
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}
