Rust Crypto Tracker is a real-time cryptocurrency price monitoring server built with Rust. This project uses the CoinAPI to fetch prices for multiple cryptocurrencies and broadcasts these updates to connected clients via WebSockets.

• Real-time cryptocurrency price updates
• Supports multiple cryptocurrencies
• WebSocket server to push updates to clients
• Asynchronous and concurrent operations with Tokio
• Uses Warp for the WebSocket server

• Rust (latest stable version)
• CoinAPI key (get it from CoinAPI)

1. Clone the repository:

   git clone https://github.com/anantdubey16/rust_crypto_tracker.git
   cd rust_crypto_tracker

2. Set your CoinAPI key: Replace your_api_key in src/main.rs with your actual CoinAPI key.

   let api_key = "your_api_key";

3. Build the project:

   cargo build

4. Run the server:

   cargo run

5. Connect to WebSocket server: Open a WebSocket client and connect to ws://127.0.0.1:3030/ws to receive real-time price updates.

This file contains the main logic of the server:

• Imports and dependencies: Includes necessary libraries and modules.
• PriceUpdate struct: Defines the structure for price updates.
• handle_connection function: Manages WebSocket connections and message broadcasting.
• main function: Initializes the server, sets up WebSocket routes, and spawns tasks for fetching prices.

This file handles communication with the CoinAPI:

• CoinApiResponse struct: Deserializes API responses.
• fetch_price function: Fetches prices from CoinAPI for given asset IDs.

• The server fetches prices for multiple cryptocurrencies (BTC, ETH, XRP, BCH, ADA, LTC, LINK, XLM, DOT, SOL) every 5 seconds.
• Clients connected to the WebSocket server will receive real-time updates in JSON format:

  {
      "asset_id": "BTC",
      "price": 45000.0
  }
