Rust Web Servers — Building HTTP Servers with Actix-Web, Axum, and Warp

DodaTech Updated 2026-06-28 1 min read

In this tutorial, you will learn about Rust Web Servers. We cover key concepts, practical examples, and best practices to help you master this topic.

Rust web frameworks like Actix-web, Axum, and Warp provide type-safe routing, middleware, and async handlers for high-performance HTTP servers.

What You'll Learn

Actix-web basics
Axum with tokio
Route handlers
JSON responses

Why It Matters

Rust web servers are among the fastest. DodaZIP uses Axum for its file processing API. Discord uses Actix-web for some services.

Real-World Use

High-performance APIs, real-time services, Microservices, Websocket servers.

use axum::{
    routing::get,
    Router, Json, extract::Path,
};
use serde::Serialize;
use std::net::SocketAddr;

#[derive(Serialize)]
struct HelloResponse {
    message: String,
}

async fn hello() -> Json<HelloResponse> {
    Json(HelloResponse {
        message: "Hello, World!".to_string(),
    })
}

async fn greet_user(Path(name): Path<String>) -> String {
    format!("Hello, {}!", name)
}

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(hello))
        .route("/greet/:name", get(greet_user));

    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    println!("Server on {}", addr);

    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}
