Detailed documentation content covering core architecture, implementation steps, and production recommendations for high-performance Rust web backends.

# Working Implementation

src/main.rs

use actix_web::{get, App, HttpResponse, HttpServer, Responder};

#[get("/")]
async fn index() -> impl Responder {
    HttpResponse::Ok().body("Hello from Actix Web!")
}

Key Architectural Takeaways

•Type safety guarantees zero runtime extractor failures.
•Thread-local worker model provides linear multi-core scalability.
