Resource Usage Tracking

This module provides functionality for tracking process resource usage, including memory and CPU utilization.

Features

• Cross-platform memory usage tracking
• CPU usage monitoring with percentage calculations
• Sampling at configurable intervals
• Historical data collection with time-series support

Example

use proc_daemon::resources::{ResourceTracker, ResourceUsage};
use std::time::Duration;

// Create a new resource tracker sampling every second
let mut tracker = ResourceTracker::new(Duration::from_secs(1));

// Get the current resource usage
let usage = tracker.current_usage();
println!("Memory: {}MB, CPU: {}%", usage.memory_mb(), usage.cpu_percent());

With tokio runtime:

#[cfg(feature = "tokio")]
async {
    // Start tracking
    tracker.start().unwrap();
     
    // ... use the tracker ...
     
    // Stop tracking when done
    tracker.stop().await;
};

With async-std runtime:

#[cfg(all(feature = "async-std", not(feature = "tokio")))]
async {
    // Start tracking
    tracker.start().unwrap();
     
    // ... use the tracker ...
     
    // Stop tracking when done
    tracker.stop();
};

Structs
