Struct controlgroup::Pid

pub struct Pid(_);

PID or thread ID for attaching a task to a cgroup.

Pid can be converted from u32 and &std::process::Child.

use controlgroup::Pid;

let pid = Pid::from(42_u32);

let child = std::process::Command::new("sleep").arg("1").spawn().unwrap();
let pid = Pid::from(&child);

Trait Implementations
