Implementations

impl VolumeStat

pub fn compute_speed(
    &self,
    volume_stat_after_this: &VolumeStat,
    interval: Duration
) -> VolumeSpeed

Calculate speed between two VolumeStat instances at different time.

extern crate mprober_lib;

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

use mprober_lib::volume;

let pre_volumes = volume::get_volumes().unwrap();

let interval = Duration::from_millis(100);

sleep(interval);

let volumes = volume::get_volumes().unwrap();

if !pre_volumes.is_empty() && !volumes.is_empty() {
    let volume_speed = pre_volumes[0].stat.compute_speed(&volumes[0].stat, interval);

    println!("Read: {:.1} B/s", volume_speed.read);
    println!("Write: {:.1} B/s", volume_speed.write);
}
