Actix-Web Rust Server

Overview

This project is a simple web server built with Actix-web, a powerful and flexible web framework for Rust. The server demonstrates basic CRUD operations, including handling JSON input and generating random values. It also includes logging functionality to track requests.

Features

• Greeting Endpoint: Returns a welcome message.
• Echo Endpoint: Echoes back a JSON message provided in the request.
• Reverse Endpoint: Reverses a string provided in the request.
• Random Endpoint: Generates a random number and returns it in a JSON response.
• Request Logging: Logs request details using Actix-web's logging middleware.

Prerequisites

• Rust (1.70.0 or later)
• Cargo (Rust's package manager)

Getting Started

Clone the Repository

git clone https://github.com/yourusername/your-repo.git
cd your-repo

Install Dependencies

Make sure you have Rust and Cargo installed, then run:

cargo build

This will download and compile the dependencies.

Run the Server

To start the server, use:

cargo run

The server will start and listen on http://127.0.0.1:8080.

• GET /: Returns a welcome message.

  • Response: 200 OK with body "Welcome to the Rust Web server!"

• POST /echo: Echoes back a JSON message.

  • Request Body:

   export RUST_LOG=actix_web=info

2. Run the server and observe the logs in your console.
