In this article, we will learn web scraping through Rust. This tutorial will focus on extracting data using this programming language and then I will talk about the advantages and disadvantages of using Rust. We will talk about these libraries in a bit. At the end of this tutorial, you will have a basic idea of how Rust works and how it can be used for web scraping. Rust is a high-level programming language designed by Mozilla. It is built with a main focus on software building.

The easiest way of doing this is to connect to an API. If the website has a free-to-use API, you can just request the information you need. This is best done with Cargo. Next, add the required libraries to the dependencies. At the end of the file, add the libraries:. Scraping a page usually involves getting the HTML code of the page and then parsing it to find the information you need.
