Struct User

Source
pub struct User {
    pub name: String,
    pub passwd: CString,
    pub uid: Uid,
    pub gid: Gid,
    pub gecos: CString,
    pub dir: PathBuf,
    pub shell: PathBuf,
}
Expand description

Representation of a User, based on libc::passwd

The reason some fields in this struct are String and others are CString is because some fields are based on the user’s locale, which could be non-UTF8, while other fields are guaranteed to conform to NAME_REGEX, which only contains ASCII.

Fields§

§name: String

Username

§passwd: CString

User password (probably hashed)

§uid: Uid

User ID

§gid: Gid

Group ID

§gecos: CString

User information

§dir: PathBuf

Home directory

§shell: PathBuf

Path to shell

Implementations§

Source§

impl User

Source

pub fn from_uid(uid: Uid) -> Result<Option<Self>>

Get a user by UID.

Internally, this function calls getpwuid_r(3)

§Examples
use nix::unistd::{Uid, User};
// Returns an Result<Option<User>>, thus the double unwrap.
let res = User::from_uid(Uid::from_raw(0)).unwrap().unwrap();
assert_eq!(res.name, "root");
Source

pub fn from_name(name: &str) -> Result<Option<Self>>

Get a user by name.

Internally, this function calls getpwnam_r(3)

§Examples
use nix::unistd::User;
// Returns an Result<Option<User>>, thus the double unwrap.
let res = User::from_name("root").unwrap().unwrap();
assert_eq!(res.name, "root");
