Struct Group

pub struct Group { /* private fields */ }

Expand description

Type containing group information.

It is returned by User::groups or Groups::list.

use sysinfo::Users;

let mut users = Users::new_with_refreshed_list();

for user in users.list() {
    println!(
        "user: (ID: {:?}, group ID: {:?}, name: {:?})",
        user.id(),
        user.group_id(),
        user.name(),
    );
    for group in user.groups() {
        println!("group: (ID: {:?}, name: {:?})", group.id(), group.name());
    }
}

Implementations§

impl Group

pub fn id(&self) -> &Gid

Returns the ID of the group.

⚠️ This information is not set on Windows.

use sysinfo::Users;

let mut users = Users::new_with_refreshed_list();

for user in users.list() {
    for group in user.groups() {
        println!("{:?}", group.id());
    }
}

pub fn name(&self) -> &str

Returns the name of the group.

use sysinfo::Users;

let mut users = Users::new_with_refreshed_list();

for user in users.list() {
    for group in user.groups() {
        println!("{}", group.name());
    }
}
