User Interaction with Command Line

Let's start developing the application now, and the first thing that comes to mind is an interface. How will the user interact with our application? We could build a graphic user interface (GUI). A GUI provides abstractions (in the form of buttons and menus) for interacting with the application. However, for our application, we’ll make do with just the command-line interface (CLI), and we’ll refine it using Rust.

In our case, we’ll need the application to ask the user what they want to build. Keeping that in mind, let’s get to building it.

Installing dependencies

We will use the crossterm crate to enhance the interactivity of the command-line interface.

Crossterm is a Rust library for building cross-platform terminal applications. It utilizes a simple and efficient API that enables us to control terminal output, input, and styling, allowing us to create text-based user interfaces. Crossterm is more commonly used for building command-line tools, games, and other terminal-based applications in Rust.

To install crossterm, add the following line to the dependencies section of the Cargo.toml file:
