How to Use std

Use std::path::Path and std::path::PathBuf to handle file system paths in a platform-independent way. Path is an immutable view of a path, while PathBuf is an owned, mutable buffer that can be modified.

use std::path::{Path, PathBuf};

fn main() {
    let path = Path::new("/home/user/docs");
    let mut path_buf = PathBuf::from("/home/user");
    
    path_buf.push("docs");
    println!("Joined path: {}", path_buf.display());
    println!("File name: {}", path.file_name().unwrap().to_string_lossy());
}

Think of Path as a read-only label on a file folder and PathBuf as a sticky note you can write on and move around. You use Path when you just need to look at a location, and PathBuf when you need to build or change a location, like adding a new folder name to the end of a path.
