Struct sysinfo::Process

pub struct Process {
    pub uid: uid_t,
    pub gid: gid_t,
    pub tasks: HashMap<Pid, Process>,
    /* private fields */
}

Struct containing information of a process.

iOS

This information cannot be retrieved on iOS due to sandboxing.

Apple app store

If you are building a macOS Apple app store, it won’t be able to retrieve this information.

Fields

uid: uid_t

User id of the process owner.

gid: gid_t

Group id of the process owner.

tasks: HashMap<Pid, Process>

Tasks run by this process.

Trait Implementations

impl Debug for Process

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

Formats the value using the given formatter.

impl Drop for Process

fn drop(&mut self)

Executes the destructor for this type.

impl ProcessExt for Process

fn kill_with(&self, signal: Signal) -> Option<bool>

Sends the given signal to the process. If the signal doesn’t exist on this platform, it’ll do nothing and will return None. Otherwise it’ll return if the signal was sent successfully.

fn name(&self) -> &str

Returns the name of the process.

fn cmd(&self) -> &[String]

Returns the command line.

fn exe(&self) -> &Path

Returns the path to the process.

fn pid(&self) -> Pid

Returns the pid of the process.

fn environ(&self) -> &[String]

Returns the environment variables of the process.

fn cwd(&self) -> &Path

Returns the current working directory.

fn root(&self) -> &Path

Returns the path of the root directory.

fn memory(&self) -> u64

Returns the memory usage (in KB).

fn virtual_memory(&self) -> u64

Returns the virtual memory usage (in KB).

fn parent(&self) -> Option<Pid>

Returns the parent pid.

fn status(&self) -> ProcessStatus

Returns the status of the processus.

fn start_time(&self) -> u64

Returns the time where the process was started (in seconds) from epoch.

fn run_time(&self) -> u64

Returns for how much time the process has been running (in seconds).

fn cpu_usage(&self) -> f32

Returns the total CPU usage (in %). Notice that it might be bigger than 100 if run on a multicore machine.

fn disk_usage(&self) -> DiskUsage

Returns number of bytes read and written to disk.

fn kill(&self) -> bool

Sends Signal::Kill to the process (which is the only signal supported on all supported platforms by this crate).
