Implementations§

Source§

impl Group

Source

pub fn new<S: AsRef<OsStr> + ?Sized>(gid: gid_t, name: &S) -> Self

Create a new Group with the given group ID and name, with the rest of the fields filled in with dummy values.

This method does not actually create a new group on the system — it should only be used for comparing groups in tests.

§Examples
use users::Group;

let group = Group::new(102, "database");
Source

pub fn gid(&self) -> gid_t

Returns this group’s ID.

§Examples
use users::Group;

let group = Group::new(102, "database");
assert_eq!(group.gid(), 102);
Source

pub fn name(&self) -> &OsStr

Returns this group’s name.

§Examples
use std::ffi::OsStr;
use users::Group;

let group = Group::new(102, "database");
assert_eq!(group.name(), OsStr::new("database"));
