Rust Code Example: A Basic Asynchronous HTTP Server with Tokio

This example demonstrates setting up a simple HTTP server using Tokio, a powerful runtime for writing asynchronous applications in Rust. It showcases Rust's capabilities for high-performance network services.


use tokio::io::{AsyncReadExt, AsyncWriteExt};
use tokio::net::TcpListener;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let listener = TcpListener::bind("127.0.0.1:8080").await?;
    println!("Server listening on http://127.0.0.1:8080");

    loop {
        let (mut socket, _) = listener.accept().await?;

        tokio::spawn(async move {
            let mut buf = vec![0; 1024];
            let mut request = String::new();

            // Read the request line by line
            loop {
                let n = match socket.read(&mut buf).await {
                    Ok(n) if n == 0 => return, // Connection closed
                    Ok(n) => n,
                    Err(e) => {
                        eprintln!("Failed to read from socket: {}", e);
                        return;
                    }
                };
                request.push_str(&String::from_utf8_lossy(&buf[..n]));
                if request.contains("\r\n\r\n") { // End of headers
                    break;
                }
                // Small optimization: if buffer isn't full, likely end of request
                if n < buf.len() {
                    break;
                }
            }
            
            println!("Received request:\n{}", request); // Log the request for debugging

            let response = b"HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\nContent-Length: 12\r\n\r\nHello, Rust!";
            if let Err(e) = socket.write_all(response).await {
                eprintln!("Failed to write to socket: {}", e);
            }
        });
    }
}

To run this, you'll need Rust and Cargo installed, and add tokio = { version = "1", features = ["full"] } to your Cargo.toml dependencies.

This Go example demonstrates building a basic HTTP server that handles requests concurrently using goroutines. It's a fundamental pattern for scalable web services in Go.


package main

import (
	"fmt"
	"log"
	"net/http"
	"time"
)

func handler(w http.ResponseWriter, r *http.Request) {
	// Simulate some work
	time.Sleep(500 * time.Millisecond)
	fmt.Fprintf(w, "Hello from Go! You requested: %s\n", r.URL.Path)
	log.Printf("Handled request for %s", r.URL.Path)
}

func main() {
	http.HandleFunc("/", handler) // Register the handler for all paths

	port := ":8080"
	fmt.Printf("Go server starting on port %s\n", port)
	
	// Start the server. log.Fatal will print the error and exit if it fails.
	log.Fatal(http.ListenAndServe(port, nil))
}

To run this, save it as main.go and execute go run main.go. You can then access it via http://localhost:8080 in your browser.

Python Code Example: A FastAPI Endpoint for a Simple ML Model

This example demonstrates building a REST API using FastAPI (version 0.104.1) to serve a pre-trained scikit-learn (version 1.3.0) model. This is a common pattern for deploying ML models in production.


from fastapi import FastAPI
from pydantic import BaseModel
from sklearn.linear_model import LogisticRegression
import numpy as np
import joblib

# Initialize FastAPI app
app = FastAPI(title="Simple ML Model API", version="1.0.0")

# --- Model Training (for demonstration, normally loaded from file) ---
# In a real scenario, you would train and save your model separately.
# For this example, we'll create a dummy model and save it.
X_train = np.array([[1, 2], [3, 4], [5, 6], [7, 8]])
y_train = np.array([0, 0, 1, 1])
model = LogisticRegression(random_state=42)
model.fit(X_train, y_train)

# Save the model to a file
model_path = "logistic_regression_model.pkl"
joblib.dump(model, model_path)
print(f"Dummy model saved to {model_path}")
# --- End Model Training ---

# Load the pre-trained model when the application starts
try:
    loaded_model = joblib.load(model_path)
    print("Model loaded successfully.")
except FileNotFoundError:
    print(f"Error: Model file '{model_path}' not found. Please ensure it's created.")
    # Exit or handle error appropriately in a real app
    loaded_model = None 

# Define input data structure using Pydantic
class PredictionInput(BaseModel):
    features: list[float]

@app.get("/", summary="Root endpoint")
async def read_root():
    return {"message": "Welcome to the ML Model API. Use /predict to make predictions."}

@app.post("/predict", summary="Make a prediction using the trained model")
async def predict_data(data: PredictionInput):
    if loaded_model is None:
        return {"error": "Model not loaded. Cannot make predictions."}

    try:
        # Convert input features to a NumPy array, reshaping for single prediction
        input_array = np.array(data.features).reshape(1, -1)
        
        # Make prediction
        prediction = loaded_model.predict(input_array).tolist()
        prediction_proba = loaded_model.predict_proba(input_array).tolist()

        return {
            "input_features": data.features,
            "prediction": prediction[0],
            "prediction_probabilities": prediction_proba[0]
        }
    except Exception as e:
        return {"error": f"Prediction failed: {str(e)}"}

# To run this:
# 1. pip install fastapi uvicorn scikit-learn joblib pydantic
# 2. Save as `main.py`
# 3. Run: `uvicorn main:app --reload`
# 4. Access docs at http://127.0.0.1:8000/docs
# 5. Test with POST request to http://127.0.0.1:8000/predict with JSON body:
#    {"features": [5.5, 6.5]}

4. Kotlin (JVM Ecosystem)

  • Learning Curve (for experienced devs): Low to Moderate. JavaScript developers can transition easily, but mastering advanced type features, generics, and effective type-driven design takes practice.

TypeScript Code Example: Type-Safe Data Fetching with Zod

This example demonstrates how to fetch data from an API and ensure its type safety using TypeScript and Zod (version 3.22.4), a schema declaration and validation library. This is crucial for building robust applications that interact with external services.


// File: src/api.ts
import { z } from 'zod'; // npm install zod

// 1. Define the schema for the expected API response using Zod
const UserSchema = z.object({
    id: z.number().int().positive(),
    name: z.string().min(1),
    email: z.string().email(),
    username: z.string().min(1),
    address: z.object({
        street: z.string(),
        suite: z.string(),
        city: z.string(),
        zipcode: z.string(),
        geo: z.object({
            lat: z.string(),
            lng: z.string(),
        }),
    }),
    phone: z.string(),
    website: z.string().url(),
    company: z.object({
        name: z.string(),
        catchPhrase: z.string(),
        bs: z.string(),
    }),
});

// 2. Infer the TypeScript type from the Zod schema
type User = z.infer<typeof UserSchema>;

// 3. Async function to fetch and validate user data
async function fetchUser(userId: number): Promise<User | null> {
    try {
        const response = await fetch(`https://jsonplaceholder.typicode.com/users/${userId}`);
        
        if (!response.ok) {
            console.error(`HTTP error! Status: ${response.status}`);
            return null;
        }

        const rawData = await response.json();
        
        // 4. Validate the raw data against the schema
        const validatedData = UserSchema.parse(rawData);
        
        console.log(`Successfully fetched and validated user ${validatedData.name}.`);
        return validatedData;

    } catch (error) {
        if (error instanceof z.ZodError) {
            console.error('Data validation failed:', error.errors);
        } else {
            console.error('Failed to fetch user data:', error);
        }
        return null;
    }
}

// 5. Example usage
async function runExample() {
    console.log("Fetching user 1...");
    const user1 = await fetchUser(1);
    if (user1) {
        console.log(`User 1 Name: ${user1.name}, Email: ${user1.email}`);
        // user1 is now guaranteed to be of type User, with all properties
        // console.log(user1.address.street); // Type-safe access
    }

    console.log("\nAttempting to fetch invalid user (ID 999)...");
    const user999 = await fetchUser(999); // This will likely return null as user 999 doesn't exist
    if (!user999) {
        console.log("User 999 not found or invalid data received.");
    }

    // Simulate an invalid response structure (e.g., missing 'email' field)
    // For a real test, you might mock the fetch call to return malformed JSON.
    // For this direct example, we'll just show what happens if validation fails.
    // In a real scenario, if the API returns {id: 1, name: "Test"}, Zod will catch it.
    console.log("\nSimulating fetch with malformed data (Zod will catch this if the API actually returns it):");
    try {
        // This part won't actually hit the API with malformed data but shows Zod's parsing
        const malformedData = { id: 1, name: "Test User", address: {} }; // Missing email, incomplete address
        // UserSchema.parse(malformedData); // This would throw a ZodError if uncommented
        console.log("If malformed data was parsed, ZodError would be thrown.");
    } catch (e) {
        if (e instanceof z.ZodError) {
