Struct Pid 

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

Process identifier

Newtype pattern around pid_t (which is just alias). It prevents bugs caused by accidentally passing wrong value.

Implementations

impl Pid

pub const fn from_raw(pid: i32) -> Pid

Creates Pid from raw pid_t.

pub fn this() -> Pid

Returns PID of calling process

pub fn parent() -> Pid

Returns PID of parent of calling process

pub const fn as_raw(self) -> i32

Get the raw pid_t wrapped by self.

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<(), Error>

Formats the value using the given formatter.

impl Display for Pid

Available on crate feature process only.

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

Formats the value using the given formatter.

impl From<Pid> for i32

Available on crate feature process only.

fn from(pid: Pid) -> i32

Converts to this type from the input type.

impl Hash for Pid

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

where __H: Hasher,

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.
