Hierarchical timing wheel for efficient timer management 用于高效定时器管理的分层时间轮

Uses 4 wheels with different granularities to cover a wide range of timeouts. 使用4个具有不同粒度的轮来覆盖大范围的超时。

Implementations

impl TimerWheel

pub fn new() -> Self

Create a new timer wheel 创建新的时间轮

pub fn cancel_timer(&self, id: u64) -> bool

Cancel a timer by ID 通过ID取消定时器

pub fn current_ticks(&self) -> u64

Get the current tick count 获取当前滴答计数

pub fn advance(&self, ticks: u64) -> usize

Advance the timer wheel by the specified number of ticks 将时间轮推进指定数量的滴答

Returns the number of timers that expired during this advancement. 返回在此推进期间到期的定时器数量。

pub fn insert_timer(&self, duration: Duration) -> TimerHandle

Insert a timer with the specified duration 插入具有指定持续时间的定时器

pub fn insert_timer_with_waker( &self, duration: Duration, waker: Waker, ) -> TimerHandle

Insert a timer with the specified duration and associated waker 插入具有指定持续时间和关联waker的定时器

pub fn next_expiration(&self) -> Option<u64>

Get the next timer expiration time in milliseconds 获取下一个定时器到期时间（毫秒）

Returns None if there are no active timers. 如果没有活动定时器则返回 None。
