Struct sysinfo::Pid

pub struct Pid(/* private fields */);

Process ID.

Can be used as an integer type by simple casting. For example:

use sysinfo::{PidExt, Pid};

// 0's type will be different depending on the platform!
let p = Pid::from(0);

// For something more "general":
let p = Pid::from_u32(0);
let i: u32 = p.as_u32();

On glibc systems this is a glibc pid_t.

On Windows systems this is a usize and represents a windows process identifier.

On unsupported systems, this is also a usize.

Trait Implementations

impl Clone for Pid

fn clone(&self) -> Pid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pid

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

Formats the value using the given formatter.

impl Display for Pid

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

Formats the value using the given formatter.

impl From<Pid> for usize

fn from(v: Pid) -> Self

Converts to this type from the input type.

impl From<usize> for Pid

fn from(v: usize) -> Self

Converts to this type from the input type.

impl FromStr for Pid

type Err = <i32 as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Pid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Pid

fn cmp(&self, other: &Pid) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Pid

fn eq(&self, other: &Pid) -> 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 PartialOrd for Pid

fn partial_cmp(&self, other: &Pid) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl PidExt for Pid

fn as_u32(self) -> u32

Allows to convert Pid into u32.

fn from_u32(v: u32) -> Self

Allows to convert a u32 into Pid.

impl Copy for Pid

impl Eq for Pid

impl StructuralPartialEq for Pid
