gecos

This is a rust library to generate and parse gecos.

We started developing this library to be used in conjunction with libnss. For example, this library is used in the guest-users nss package.

Install

Simply install via cargo:

cargo add gecos

Usage

For a full reference, please check out the [Gecos] struct.

use std::convert::TryFrom;
use gecos::{Gecos, GecosSanitizedString};

// read gecos string from passwd etc.
let raw_gecos_string = "Some Person,Room,Work phone,Home phone,Other 1,Other 2";

let mut gecos = Gecos::from_gecos_string(raw_gecos_string).unwrap();

// access fields like
//         var   field     option   for comp
assert_eq!(gecos.full_name.as_ref().unwrap().to_string(), "Some Person");

// and you even can convert it back to a raw gecos string
assert_eq!(gecos.to_gecos_string(), raw_gecos_string);

// modifying fields work like this
gecos.full_name = Some("Another name".to_string().try_into().unwrap());
// or more explicitly
gecos.room = Some(GecosSanitizedString::new("St. 9".to_string()).unwrap());

assert_eq!(gecos.full_name.as_ref().unwrap().to_string(), "Another name");
assert_eq!(gecos.room.as_ref().unwrap().to_string(), "St. 9");
