Struct CtxSwitch

pub struct CtxSwitch {
    pub record_id: Option<RecordId>,
    pub info: Switch,
}

Process context switched.

Examples

use std::thread;
use std::time::Duration;

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.ctx_switch = true;

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

counter.enable().unwrap();

// Triggers a context switch.
thread::sleep(Duration::from_millis(1));

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