Implementations

impl CyclesReader

pub fn new(cpus: &[c_int]) -> Result<Self, &'static str>

创建CyclesReader

use cpu_cycles_reader::CyclesReader;
let reader = CyclesReader::new(&[0, 1, 2, 3]);

pub fn enable(&self)

开启Cycles监视

use cpu_cycles_reader::CyclesReader;
let reader = CyclesReader::new(&[0, 1, 2, 3]).unwrap();
reader.enable();

pub fn disable(&self)

关闭Cycles监视

use cpu_cycles_reader::CyclesReader;
let reader = CyclesReader::new(&[0, 1, 2, 3]).unwrap();
reader.disable();

pub fn read(&self) -> Result<HashMap<c_int, c_ll>, &'static str>

读取从开启到现在的Cycles数 按照构造函数cpu参数顺序返回
