Struct cpu_cycles_reader::CyclesReader

pub struct CyclesReader { /* private fields */ }

Implementations

impl CyclesReader

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

Create CyclesReader

use cpu_cycles_reader::CyclesReader;

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

pub fn enable(&self)

Enable Cycles monitoring

use cpu_cycles_reader::CyclesReader;

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

pub fn disable(&self)

Disable Cycles monitoring

use cpu_cycles_reader::CyclesReader;

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

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

Read the number of Cycles from start to present

According to the CPU number, it is collected as a std::collections::HashMap, which is convenient for on-demand reading
