Required methods

pub fn kill(&self, signal: Signal) -> bool[src]

Sends the given signal to the process.

use sysinfo::{ProcessExt, Signal, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    process.kill(Signal::Kill);
}

pub fn name(&self) -> &str[src]

Returns the name of the process.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{}", process.name());
}

pub fn cmd(&self) -> &[String]ⓘ

Notable traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
[src]

Returns the command line.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{:?}", process.cmd());
}

pub fn exe(&self) -> &Path[src]

Returns the path to the process.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{}", process.exe().display());
}

pub fn pid(&self) -> i32[src]

Returns the pid of the process.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{}", process.pid());
}

pub fn environ(&self) -> &[String]ⓘ

Notable traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
[src]

Returns the environment of the process.

Always empty on Windows, except for current process.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{:?}", process.environ());
}

pub fn cwd(&self) -> &Path[src]

Returns the current working directory.

Always empty on Windows.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{}", process.cwd().display());
}

pub fn root(&self) -> &Path[src]

Returns the path of the root directory.

Always empty on Windows.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{}", process.root().display());
}

pub fn memory(&self) -> u64[src]

Returns the memory usage (in kB).

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{} kB", process.memory());
}

pub fn virtual_memory(&self) -> u64[src]

Returns the virtual memory usage (in kB).

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{} kB", process.virtual_memory());
}

pub fn parent(&self) -> Option<i32>[src]

Returns the parent pid.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{:?}", process.parent());
}

pub fn status(&self) -> ProcessStatus[src]

Returns the status of the processus.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{:?}", process.status());
}

pub fn start_time(&self) -> u64[src]

Returns the time of process launch (in seconds).

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("Running since {} seconds", process.start_time());
}

pub fn cpu_usage(&self) -> f32[src]

Returns the total CPU usage (in %).

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    println!("{}%", process.cpu_usage());
}

pub fn disk_usage(&self) -> DiskUsage[src]

Returns number of bytes read and written to disk.

/!\ On Windows, this method actually returns ALL I/O read and written bytes.

use sysinfo::{ProcessExt, System, SystemExt};

let s = System::new();
if let Some(process) = s.get_process(1337) {
    let disk_usage = process.disk_usage();
    println!("read bytes   : new/total => {}/{}",
        disk_usage.read_bytes,
        disk_usage.total_read_bytes,
    );
    println!("written bytes: new/total => {}/{}",
        disk_usage.written_bytes,
        disk_usage.total_written_bytes,
    );

Implementations on Foreign Types

impl ProcessExt for Process[src]

pub fn status(&self) -> ProcessStatus[src]

Returns the status of the processus (idle, run, zombie, etc). None means that sysinfo doesn’t have enough rights to get this information.
