定时器管理器 trait，定义平台无关的定时调度能力契约。 支持一次性定时和重复定时的创建与取消。 内部基于 tokio::sync::Notify（条件变量机制）实现触发。

Required Methods

fn set_timer<'life0, 'async_trait>( &'life0 self, delay: Duration, mode: TimerMode, callback: TimerCallback, ) -> Pin<Box<dyn Future<Output = Result<TimerId, HostApiError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

创建一个定时器。

参数：

• delay: 延迟时长（OneShot 为触发延迟，Interval 为重复间隔）
• mode: 定时模式（一次性或重复）
• callback: 触发时调用的回调函数，接收 TimerId 作为参数

返回：TimerId，可用于后续取消定时器。

fn cancel_timer<'life0, 'async_trait>( &'life0 self, id: TimerId, ) -> Pin<Box<dyn Future<Output = Result<(), HostApiError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

取消指定 ID 的定时器。

参数：id - 要取消的定时器 ID。 返回：成功返回 Ok(())，定时器不存在时也返回 Ok(())。

fn cancel_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), HostApiError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

取消所有定时器。

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
