Adding `wae_event` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add wae-event

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

wae-event = "0.0.2"

The wae_event library will be automatically available globally. Read the wae_event library documentation.

Readme

wae-event

事件模块 - 提供事件驱动架构支持。

主要功能

事件发布/订阅: 解耦的事件通信机制
异步处理: 非阻塞事件处理
多订阅者: 支持多个订阅者监听同一事件
类型安全: 强类型事件定义

技术栈

异步运行时: Tokio
序列化: serde

使用示例

use wae_event::{EventBus, EventHandler, Event};

#[derive(Debug, Clone, Event)]
struct UserCreated {
    user_id: String,
    username: String,
}

struct SendWelcomeEmail;

impl EventHandler<UserCreated> for SendWelcomeEmail {
    async fn handle(&self, event: &UserCreated) {
        println!("发送欢迎邮件给: {}", event.username);
    }
}

#[tokio::main]
async fn main() {
    let bus = EventBus::new();
    
    bus.subscribe::<UserCreated>(SendWelcomeEmail);
    
    bus.publish(UserCreated {
        user_id: "001".to_string(),
        username: "张三".to_string(),
    }).await;
}

事件流程

发布者调用 publish 发布事件
EventBus 查找所有订阅者
异步执行所有订阅者的 handle 方法
