Simple REST API — Rocket Code

Demonstrates a simple Rocket application with routes for listing and creating Todo items using type-safe request handling.

#[macro_use] extern crate rocket;
use rocket::serde::{json::Json, Deserialize, Serialize};
use std::sync::Mutex;

#[derive(Serialize, Deserialize, Clone)]
struct Todo {
    id: u32,
    title: String,
    completed: bool,
}

struct AppState {
    todos: Mutex<Vec<Todo>>,
}

#[get("/todos")]
fn get_todos(state: &rocket::State<AppState>) -> Json<Vec<Todo>> {
    let todos = state.todos.lock().unwrap();
    Json(todos.clone())
}

#[post("/todos", format = "json", data = "todo")]
fn add_todo(todo: Json<Todo>, state: &rocket::State<AppState>) {
    let mut todos = state.todos.lock().unwrap();
    todos.push(todo.into_inner());
}

#[launch]
fn rocket() -> _ {
    rocket::build()
        .manage(AppState { todos: Mutex::new(Vec::new()) })
        .mount("/", routes![get_todos, add_todo])
}

Rocket Language Guide

Rocket is a Rust-based web framework designed for type-safe, fast, and secure web applications and APIs.

Primary Use Cases

▸Building type-safe web APIs
▸High-performance backend services
▸Server-side applications with Rust safety guarantees
▸RESTful and GraphQL APIs
▸Applications requiring strict compile-time checks

Notable Features

▸Type-safe routing and request guards
▸Built-in JSON and form data handling
▸Asynchronous request handling
▸Template rendering support (Tera, Handlebars)
▸Fairings and request/response hooks for extensibility

Origin & Creator

Created by Sergio Benitez in 2016, Rocket is maintained by the Rust community and open-source contributors.

Industrial Note

Rocket is particularly suited for high-performance web applications where safety, speed, and Rust’s memory guarantees are critical, such as fintech, embedded web services, and high-throughput APIs.
