Struct Process

pub struct Process {
    pub pid: Option<i32>,
    pub ppid: Option<i32>,
    pub cmdline: Vec<String>,
    pub cmdline_is_comm: Option<bool>,
    pub uid: Option<i32>,
    pub nspid: Vec<i32>,
    pub process_start_from_boot: Option<u64>,
    pub is_kthread: Option<bool>,
}

Representation of a process.

Fields

pid: Option<i32>

The UNIX process ID, aka thread group ID (as per getpid()) in the root PID namespace.

ppid: Option<i32>

The parent process ID, as per getppid().

cmdline: Vec<String>

The command line for the process, as per /proc/pid/cmdline, broken up on NUL bytes. If it is a kernel thread or a zombie, there will only be one cmdline field and it will contain /proc/pid/comm.

cmdline_is_comm: Option<bool>

If true, the |cmdline| field was filled with the main thread’s “comm” field instead. Introduced in: perfetto v50.

uid: Option<i32>

The uid for the process, as per /proc/pid/status.

nspid: Vec<i32>

The non-root-level process IDs if the process runs in a PID namespace. Read from the NSpid entry of /proc//status, with the first element (root-level process ID) omitted.

process_start_from_boot: Option<u64>

Timestamp of when the process was created, in nanoseconds from boot. Parsed from starttime in /proc/pid/stat. Recorded if record_process_age config option is set. Resolution of “clock ticks”, usually 10ms.

is_kthread: Option<bool>

If true, the process is a kernel thread. Set only on linux v6.4+. For traces from older devices, it is possible to infer most kthreads by checking that they’re a descendant of kthreadd (pid=2), or are the idle process (pid=0). Introduced in: perfetto v50.

Implementations

impl Process

pub fn pid(&self) -> i32

Returns the value of pid, or the default value if pid is unset.

pub fn ppid(&self) -> i32

Returns the value of ppid, or the default value if ppid is unset.

pub fn uid(&self) -> i32

Returns the value of uid, or the default value if uid is unset.

pub fn process_start_from_boot(&self) -> u64

Returns the value of process_start_from_boot, or the default value if process_start_from_boot is unset.

pub fn is_kthread(&self) -> bool

Returns the value of is_kthread, or the default value if is_kthread is unset.

pub fn cmdline_is_comm(&self) -> bool

Returns the value of cmdline_is_comm, or the default value if cmdline_is_comm is unset.

Trait Implementations

impl Clone for Process

fn clone(&self) -> Process

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Process

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

Formats the value using the given formatter.

impl Default for Process

fn default() -> Self

Returns the “default value” for a type.

impl Message for Process

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Process

fn eq(&self, other: &Process) -> 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.
