Follow these steps:

1. Open the Cargo.toml file that was generated earlier for you.

2. Under [dependencies], add the following line:

glob = "0.2.11"

3. If you want, you can go to glob's crates.io page (https://crates.io/crates/glob) to check for the newest version and use that one instead.

4. In the bin folder, create a file called glob.rs.

5. Add the following code and run it with cargo run --bin glob:

1    extern crate glob;
2    use glob::{glob, glob_with, MatchOptions};
3 
4    fn main() {
5      println!("All all Rust files in all subdirectories:");
6      for entry in glob("**/*.rs").expect("Failed to read glob
       pattern") {
7        match entry {
8          Ok(path) => println!("{:?}", path.display()),
9          Err(e) => println!("Failed to read file: {:?}", e),
10       }
11     }
12 
13     // Set the glob to be case insensitive and ignore hidden
          files
14     let options = MatchOptions...
