Informazioni di sistema in Rust con systemstat

systemstat è un modulo per Rust per ottenere informazioni di sistema.

Difficilmente ho trovato un modulo / libreria cosi completo; anche paragonandolo ad altri linguaggi.

Infatti vi riporto direttamente il codice che trovate su GitHub, perchè contiene praticamente tutto.

Ed è anche facile da capire.

Per installarlo agigungete questa dipendenza a Cargo.toml:

[dependencies]
systemstat = "*"

Questo il codice:

extern crate systemstat;

use std::thread;
use std::time::Duration;
use systemstat::{System, Platform, saturating_sub_bytes};

fn main() {
    let sys = System::new();

            for mount in mounts.iter() {
                println!("{} ---{}---> {} (available {} of {})",
                         mount.fs_mounted_from, mount.fs_type, mount.fs_mounted_on, mount.avail, mount.total);
            }
        }
        Err(x) => println!("Mounts: error: {}", x)
    }

    match sys.block_device_statistics() {

            thread::sleep(Duration::from_secs(1));
            let cpu = cpu.done().unwrap();
            println!("CPU load: {}% user, {}% nice, {}% system, {}% intr, {}% idle ",
                     cpu.user * 100.0, cpu.nice * 100.0, cpu.system * 100.0, cpu.interrupt * 100.0, cpu.idle * 100.0);
