use std::os::unix::fs::DirEntryExt2;
use std::{fs, io};

fn main() -> io::Result<()> {
    let mut entries = fs::read_dir(".")?.collect::<Result<Vec<_>, io::Error>>()?;
    entries.sort_unstable_by(|a, b| a.file_name_ref().cmp(b.file_name_ref()));

    for p in entries {
        println!("{:?}", p);
    }
