任务插件

管理 TaskWorker 和 RetryScanner 的生命周期。 持久化通过 TaskStorage trait 委托给业务方。

实现 alun_core::Plugin,可通过 PluginManagerApp::plugin() 统一管理。

§使用示例

// 配置从 config.toml 的 [task] section 读取
let task_cfg: TaskWorkerConfig = app.config().get_section("task")?;
let storage = Arc::new(DbTaskStorage::new());
let task_plugin = TaskPlugin::new(task_cfg, storage, registry)?;
app.plugin(task_plugin).scan().start().await

Implementations§

Source§

impl TaskPlugin

Source

pub fn new( config: TaskWorkerConfig, storage: Arc<dyn TaskStorage>, registry: HandlerRegistry, ) -> Result<Self, String>

创建任务插件

  • config: TaskWorker 运行时配置(建议从 [task] section 读取,支持 Deserialize)
  • storage: 由业务方实现的持久化接口
  • registry: 已注册 handler 的注册中心
Source

pub fn metrics(&self) -> Arc<TaskMetrics>

返回任务指标(供外部查询)

Source

pub fn topics(&self) -> &[String]

返回已注册的 topic 列表
