Struct Process

pub struct Process {
    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

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 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 bytes).

fn virtual_memory(&self) -> u64

Returns the virtual memory usage (in bytes).

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

Returns the parent PID.

fn status(&self) -> ProcessStatus

Returns the status of the process.

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 multi-core machine.

fn disk_usage(&self) -> DiskUsage

Returns number of bytes read and written to disk.

fn user_id(&self) -> Option<&Uid>

Returns the ID of the owner user of this process or None if this information couldn’t be retrieved. If you want to get the User from it, take a look at SystemExt::get_user_by_id.

fn effective_user_id(&self) -> Option<&Uid>

Returns the user ID of the effective owner of this process or None if this information couldn’t be retrieved. If you want to get the User from it, take a look at SystemExt::get_user_by_id.

fn group_id(&self) -> Option<Gid>

Returns the process group ID of the process.

fn effective_group_id(&self) -> Option<Gid>

Returns the effective group ID of the process.

fn wait(&self)

Wait for process termination.

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

Returns the session ID for the current process or None if it couldn’t be retrieved.

fn kill(&self) -> bool

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