Trait TimerCallback 

pub trait TimerCallback:
    Send
    + Sync
    + 'static {
    // Required method
    fn call(&self) -> Pin<Box<dyn Future<Output = ()> + Send>>;
}

Timer Callback Trait

Types implementing this trait can be used as timer callbacks.

可实现此特性的类型可以作为定时器回调函数。

Examples (示例)

use kestrel_timer::TimerCallback;
use std::future::Future;
use std::pin::Pin;
 
struct MyCallback;
 
impl TimerCallback for MyCallback {
    fn call(&self) -> Pin<Box<dyn Future<Output = ()> + Send>> {
        Box::pin(async {
            println!("Timer callback executed!");
        })
    }
}

Required Methods

fn call(&self) -> Pin<Box<dyn Future<Output = ()> + Send>>

Execute callback, returns a Future

执行回调函数，返回一个 Future

Implementors

impl<F, Fut> TimerCallback for F

where F: Fn() -> Fut + Send + Sync + 'static, Fut: Future<Output = ()> + Send + 'static,

Implement TimerCallback trait for closures

Supports Fn() -> Future closures, can be called multiple times, suitable for periodic tasks

实现 TimerCallback 特性的类型，支持 Fn() -> Future 闭包，可以多次调用，适合周期性任务
