Struct zellij_server::os_input_output::Pid

pub struct Pid(_);

Process identifier

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

Implementations

impl Pid

pub 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 fn as_raw(self) -> i32

Get the raw pid_t wrapped by self.

Trait Implementations

impl Clone for Pid

pub 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

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

Formats the value using the given formatter.

impl Display for Pid

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

Formats the value using the given formatter.

impl Hash for Pid

pub 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, 

Feeds a slice of this type into the given Hasher.

impl Ord for Pid

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<Pid> for Pid

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Pid> for Pid

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

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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