Show all directory content in python and rust

In Python, you can make use of the Path class from pathlib module:

from pathlib import Path

p = Path("/home/eric")

for item in p.iterdir():
    print(item)

Output:

.rustup
.config
.bash_logout
snap
.cert
.sudo_as_admin_successful
.mozilla
Music
.bashrc
.gnupg
.cache
.pki
Documents
.bash_aliases
.tmux.conf
.vscode
.vimrc

.dbus

.bash_history
.pam_environment
.cargo
.python_history

Rust has something similar: std::path::Path.

Since Python's Path object has an iterdir() method, I naturally tried to use iter method for std::path::Path. But it returns an iterator of path components:

use std::path::Path;

let folder = Path::new("/home/eric");

for component in folder.iter() {
    println!("{:?}", component);
}

Output:

"/"
"home"
"eric"

What I actually want is the read_dir method.

read_dir returns a Result-wrapped iterator of Result-wrapped DirEntry.

They are wrapped in Result<T, err> because reading from disk can sometimes result in an IO error. Since this is not production code, I'll unwrap these Result enums.

use std::path::Path;
use std::fs::DirEntry;

let folder = Path::new("/home/eric");

for item in folder.read_dir().unwrap() {
    let entry: DirEntry = item.unwrap();
    println!("{:?}", entry.file_name());
}

Output (identical to that of Python's output):

.rustup
.config
.bash_logout
snap
.cert
.sudo_as_admin_successful
.mozilla
Music
.bashrc
.gnupg
.cache
.pki
