    pub record_id: Option<RecordId>,
    pub id: u64,
    pub path: CString,
}

Examples

Running this example may require root privileges.

use perf_event_open::config::{Cpu, Opts, Proc};
use perf_event_open::count::Counter;
use perf_event_open::event::sw::Software;

let event = Software::Dummy;
let target = (Proc::CURRENT, Cpu::ALL);
let mut opts = Opts::default();
opts.extra_record.cgroup = true;

let counter = Counter::new(event, target, opts).unwrap();
let sampler = counter.sampler(5).unwrap();

counter.enable().unwrap();
let path = format!("/sys/fs/cgroup/{}", uuid::Uuid::new_v4());
std::fs::create_dir(&path).unwrap();
std::fs::remove_dir(&path).unwrap();

for it in sampler.iter() {
    println!("{:-?}", it);
}
