Struct Pid 

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

Process ID.

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

use sysinfo::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.

Implementations

impl Pid

pub fn as_u32(self) -> u32

Allows to convert Pid into u32.

use sysinfo::Pid;

let pid = Pid::from_u32(0);
let value: u32 = pid.as_u32();

pub fn from_u32(v: u32) -> Self

Allows to convert a u32 into Pid.

use sysinfo::Pid;

let pid = Pid::from_u32(0);

Trait Implementations

impl Clone for Pid

fn clone(&self) -> Pid

Returns a duplicate 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,

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 Copy for Pid

impl Eq for Pid

impl StructuralPartialEq for Pid

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
