Struct ProcessLink 

pub struct ProcessLink { /* private fields */ }

A single entry in a process ancestry chain.

Displayed as "pid|cmd|user" by the Display impl.

use proc_tree::ProcessLink;

let link = ProcessLink::new(102, "touch".into(), "touch /tmp/foo".into(), "root".into());
assert_eq!(link.to_string(), "102|touch /tmp/foo|root");
assert_eq!(link.pid(), 102);
assert_eq!(link.comm(), "touch");
assert_eq!(link.cmd(), "touch /tmp/foo");
assert_eq!(link.user(), "root");

A chain is a Vec<ProcessLink> ordered from child to ancestor.

Implementations

impl ProcessLink

pub fn new(pid: u32, comm: String, cmd: String, user: String) -> ProcessLink

Create a new ProcessLink.

pub fn pid(&self) -> u32

The PID of the process.

pub fn comm(&self) -> &str

Binary name (from /proc/{pid}/comm).

pub fn cmd(&self) -> &str

The command name of the process.

pub fn user(&self) -> &str

The username of the process.

Trait Implementations

impl Clone for ProcessLink

fn clone(&self) -> ProcessLink

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcessLink

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProcessLink

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProcessLink, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProcessLink

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

Formats the value using the given formatter.

impl Eq for ProcessLink

impl PartialEq for ProcessLink

fn eq(&self, other: &ProcessLink) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ProcessLink

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
