pub trait Process: Drop {
#[must_use]    fn id(&self) -> u32;
}

The trait returned by PipedSpwner::spawn_owned().

All implementations of [PipedSpawner] return a concrete instance capable of read/write.

Required methods

#[must_use]fn id(&self) -> u32

Returns the OS-assigned process identifier associated with this child.

Examples

Basic usage:

use std::process::Command;
use pwner::{ Spawner, Process };

let mut command = Command::new("ls");
if let Ok(child) = command.spawn_owned() {
    println!("Child's ID is {}", child.id());
} else {
    println!("ls command didn't start");
