SpawnTask

Struct SpawnTask 

Source
pub struct SpawnTask { /* private fields */ }
Expand description

Spawn 任务

用于包装已经构建好的 Future(例如 gRPC server) 用户可以在 service 层构建好 Future,然后通过 runtime 管理

§特性

  • 支持依赖声明
  • 支持 shutdown 信号
  • 支持优先级设置
  • 支持关键任务标记

§示例

§不需要 shutdown 的任务

use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::new("my-task", async {
    // 任务逻辑
    Ok(())
});

§需要 shutdown 的任务

use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::with_shutdown("my-grpc", |shutdown_rx| {
    async move {
        // 使用 shutdown_rx 实现优雅停机
        let _ = shutdown_rx.await;
        Ok(())
    }
});

§带依赖的任务

use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::new("task-b", async { Ok(()) })
    .with_dependencies(vec!["task-a".to_string()])
    .with_priority(10)
    .with_critical(true);

Implementations§

Source§

impl SpawnTask

Source

pub fn new<Fut>(name: impl Into<String>, future: Fut) -> Self
where Fut: Future<Output = TaskResult> + Send + 'static,

创建新的 spawn 任务(不需要 shutdown_rx)

§参数
  • name - 任务名称
  • future - 要运行的 Future(不依赖 shutdown_rx)
§示例
use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::new("my-task", async {
    // 任务逻辑
    Ok(())
});
Source

pub fn with_shutdown<F, Fut>(name: impl Into<String>, future_fn: F) -> Self
where F: FnOnce(Receiver<()>) -> Fut + Send + 'static, Fut: Future<Output = TaskResult> + Send + 'static,

创建新的 spawn 任务(需要 shutdown_rx)

§参数
  • name - 任务名称
  • future_fn - 闭包,接收 shutdown_rx,返回 Future
§示例
use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::with_shutdown("my-task", |shutdown_rx| {
    async move {
        // 使用 shutdown_rx
        let _ = shutdown_rx.await;
        Ok(())
    }
});
Source

pub fn with_dependencies(self, deps: Vec<String>) -> Self

设置任务依赖

§参数
  • deps - 依赖的任务名称列表
§示例
use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::new("task-b", async { Ok(()) })
    .with_dependencies(vec!["task-a".to_string()]);
Source

pub fn with_priority(self, priority: i32) -> Self

设置任务优先级

§参数
  • priority - 优先级(数值越大优先级越高)
§示例
use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::new("my-task", async { Ok(()) })
    .with_priority(10);
Source

pub fn with_critical(self, critical: bool) -> Self

设置是否为关键任务

§参数
  • critical - 是否为关键任务
§示例
use flare_core_runtime::task::SpawnTask;

let task = SpawnTask::new("my-task", async { Ok(()) })
    .with_critical(true);
