Struct CpuLoad 

pub struct CpuLoad { /* private fields */ }

CPU Load Monitor CPU 负载监控器

Implementations

impl CpuLoad

pub fn new() -> Self

Create monitor with default 1s interval 使用默认 1 秒间隔创建监控器

pub fn init(interval: Duration) -> Self

Create monitor and start background sampling task 创建监控器并启动后台采样任务

pub fn idlest(&self) -> usize

Get the index of the idlest CPU core (Round-Robin with periodic re-sort) 获取最空闲的 CPU 核心索引（轮询 + 周期性重排序）

pub fn global(&self) -> u8

Get the current global CPU load (0-100) 获取当前全局 CPU 负载 (0-100)

pub fn core(&self, idx: usize) -> Option<u8>

Get the load of a specific core (0-100) 获取指定核心的负载 (0-100)

pub fn len(&self) -> usize

Get the number of CPU cores 获取 CPU 核心数

pub fn is_empty(&self) -> bool

Check if no cores (always false in practice) 检查是否无核心（实际上总是 false）
