Child

Implementations

impl Fork

pub const fn is_parent(&self) -> bool

Returns true if this is the parent process

Examples

use fork::{fork, Fork};

match fork() {
    Ok(result) => {
        if result.is_parent() {
            println!("I'm the parent");
        }
    }
    Err(_) => {}
}

pub const fn is_child(&self) -> bool

Returns true if this is the child process

Examples

use fork::{fork, Fork};

match fork() {
    Ok(result) => {
        if result.is_child() {
            println!("I'm the child");
            std::process::exit(0);
        }
    }
    Err(_) => {}
}

pub const fn child_pid(&self) -> Option<pid_t>

Returns the child PID if this is the parent, otherwise None

Examples

use fork::{fork, Fork};

match fork() {
    Ok(result) => {
        if let Some(child_pid) = result.child_pid() {
            println!("Child PID: {}", child_pid);
        }
    }
    Err(_) => {}
}

Trait Implementations

impl Clone for Fork

fn clone(&self) -> Fork

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fork

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

Formats the value using the given formatter.

impl Hash for Fork

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 PartialEq for Fork

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