Delete/Empty The Files Inside A Directory Recursively In Rust

This function empties a directory. Everything inside it is removed but the directory itself remains. Errors occur if the target directory doesn't exist or if something inside it can't be deleted.

Reminder

This code removes files recursively without asking for confirmation. Make sure to double check the path you're working on to make sure your code is pointing to the correct place.

Output:
