Rust Code Overview

The API is implemented in Rust programming language using Actix web framework and MongoDB driver. Below are the key components of the Rust code:

• User Struct: Represents a user with username and password fields.

• register Function: Handles user registration by inserting user data into the MongoDB collection. It takes user data and the MongoDB collection as arguments and returns a HTTP response indicating the registration status.

• login Function: Handles user login by verifying user credentials against the MongoDB collection. It takes user data and the MongoDB collection as arguments and returns a HTTP response indicating the login status.

• main Function: Initializes the Actix web server, connects to the MongoDB database, selects the 'users' collection, and binds the routes for registration and login.

Usage

1. Make sure Rust and MongoDB are installed on your system.
2. Run cargo run to start the API server.
3. Send POST requests to /register and /login endpoints using JSON body to register and login users.

MongoDB Configuration

Update the MongoDB connection URI in the main function with your MongoDB Atlas credentials and cluster information.

let client = Client::with_uri_str("mongodb+srv://<username>:<password>@<cluster>/<database>")
    .await
    .expect("Failed to initialize MongoDB client");

Replace <username>, <password>, and with your MongoDB Atlas credentials and cluster information.
