Hello, I'm trying to write a ls like functionality in

rust for learning.
It just prints files of current directory.

I'm unable to print OsStr (returned by file_name()) as it does not have Display trait. How to print then?

Code is here:

use std::{env, fs, path::PathBuf};

fn main() {
let path = env::current_dir().unwrap();
let items = get_dir_items(&path);

for item in items {
println!("{}", item.file_name().unwrap())
}
}

fn get_dir_items(path: &PathBuf) -> Vec<PathBuf> {
let items: Vec<PathBuf> = fs::read_dir(path)
.unwrap()
.map(|item| item.unwrap())
.map(|entry| entry.path())
.collect();
items
}
