Async HTTP Requester

A high-performance command-line tool that asynchronously fetches cryptocurrency price data from the CoinGecko API.

Overview

This project demonstrates efficient handling of concurrent HTTP requests in Rust, utilizing modern asynchronous programming patterns. It allows users to fetch real-time cryptocurrency price data for multiple tokens simultaneously.

Features

• Asynchronous HTTP requests using tokio and reqwest
• Integration with CoinGecko's public API
• Concurrent price fetching for multiple cryptocurrencies
• Robust error handling and request rate limiting
• Structured logging for debugging and monitoring
• Comprehensive test coverage including integration tests

Architecture

The application is built with the following components:

• HTTP Client Layer: Handles API communication using reqwest
• Rate Limiter: Ensures compliance with CoinGecko's API limits
• Data Models: Type-safe representations of API responses
• Error Handling: Custom error types for better error management
• CLI Interface: User-friendly command-line interface
