Featured Building High-Performance APIs with Rust

Rust Overview

Rust is a systems programming language focused on safety, speed, and concurrency, perfect for building high-performance APIs.

Setting Up Rust API

# Install Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Create new project
cargo new my-api
cd my-api

Basic Actix-Web Server

use actix_web::{web, App, HttpResponse, HttpServer};
use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize)]
struct User {
    id: u32,
    name: String,
    email: String,
}

async fn get_users() -> Result<HttpResponse> {
    let users = vec![
        User {
            id: 1,
            name: "John".to_string(),
            email: "john@example.com".to_string(),
        }
    ];
    Ok(HttpResponse::Ok().json(users))
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new()
            .route("/api/users", web::get().to(get_users))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

Best Practices

• Leverage Rust's memory safety
• Use async/await for I/O
• Implement proper error handling
• Use serde for serialization
• Take advantage of Rust's performance
