• find a spot for the following
• also cover std implementation

remove_dir_all

A safe, reliable implementation of remove_dir_all for Windows

use std::io;

// This library provides an alternative implementation of
// std::fs::remove_dir_all from the Rust std library.
use remove_dir_all::remove_dir_all;

fn main() -> io::Result<()> {
    // Create a directory structure for demonstration (if it doesn't exist
    // already)
    std::fs::create_dir_all("temp/example_dir/sub_dir")?;
    std::fs::write("temp/example_dir/file1.txt", "Hello, world!")?;
    std::fs::write("temp/example_dir/sub_dir/file2.txt", "Rust is awesome!")?;

    println!("Directory and files created successfully!");

    // Now, remove the directory and all of its contents
    match remove_dir_all("temp/example_dir") {
        Ok(_) => println!(
            "Directory 'example_dir' and all contents removed successfully!"
        ),
        Err(e) => eprintln!("Failed to remove directory 'example_dir': {}", e),

    Ok(())
