Struct nix::unistd::User

pub struct User {
    pub name: String,
    pub passwd: CString,
    pub uid: Uid,
    pub gid: Gid,
    pub gecos: CString,
    pub dir: PathBuf,
    pub shell: PathBuf,
    pub class: CString,
    pub change: time_t,
    pub expire: time_t,
}

Available on crate feature user only.

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

class: CString

Login class

change: time_t

Last password change

expire: time_t

Expiration time of account

Implementations

impl User

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");

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");

Trait Implementations

impl Clone for User

fn clone(&self) -> User

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for User

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&passwd> for User

fn from(pw: &passwd) -> User

Converts to this type from the input type.

impl From<User> for passwd

fn from(u: User) -> Self

Converts to this type from the input type.

impl PartialEq<User> for User

fn eq(&self, other: &User) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
