This is only for reading CpuCycles specialization, not a complete package of perf_event_read

Example:

use std::{fs, time::{Duration, Instant}, thread};
use cpu_cycles_reader::{Cycles, CyclesReader, CyclesInstant};

let reader = CyclesReader::new().unwrap();
let record_1 = reader.instant(0).unwrap();

thread::sleep(Duration::from_secs(1));

let record_2 = reader.instant(0).unwrap();
let cycles = record_2 - record_1;

println!("{cycles}");
