Sure, here's an expanded version of the first project idea:

The goal of the project is to build a command-line tool that scrapes data from a website and saves it to a CSV file using the Rust programming language. You can start by identifying a website that has publicly available data, such as a news website that publishes articles in a specific category.

To build the tool, you'll need to use the reqwest library to make HTTP requests and the csv library to read and write CSV files. Here are the high-level steps to get started:

Start by creating a new Rust project using Cargo, Rust's build system and package manager.
Use the reqwest library to make a GET request to the website you want to scrape. The response will be in HTML format.
Use a Rust HTML parsing library, such as scraper, to extract the relevant data from the HTML response. For example, you might extract the title, author, and publication date of each article on the page.
Use the csv library to write the extracted data to a CSV file. You can create a new file or append to an existing file, depending on your needs.
As you build the tool, consider adding error handling and input validation to make the tool more robust and user-friendly. You might also consider using command-line argument parsing libraries like clap to allow the user to specify which website to scrape, which category of articles to extract, and so on.

Overall, this project will allow you to practice using Rust's HTTP and HTML parsing libraries, as well as working with files and error handling. It is a useful tool that can be customized to scrape data from a variety of websites, making it a valuable addition to your programming toolkit.
