基于Future(MVP),用于为外部提供基础的通用异步运行时和工具

主要特征

  • 任务池: 可定制的任务池
  • 任务ID: 外部使用任务ID可以很方便的唤醒和挂起
  • 抽象接口: 可以自由实现自己的运行时
  • 运行时推动:单线程运行时可以用自己的方式推动运行

Examples

本地异步运行时:

 use pi_async::rt::{AsyncRuntime, AsyncRuntimeExt, serial_local_thread::{LocalTaskRunner, LocalTaskRuntime}};
 let rt = LocalTaskRunner::<()>::new().into_local();
 let _ = rt.block_on(async move {});

多线程异步运行时使用:

 use pi_async::prelude::{MultiTaskRuntime, MultiTaskRuntimeBuilder, StealableTaskPool};
 use pi_async::rt::AsyncRuntimeExt;

 let pool = StealableTaskPool::with(4,100000,[1, 254],3000);
 let builer = MultiTaskRuntimeBuilder::new(pool)
     .set_timer_interval(1)
     .init_worker_size(4)
     .set_worker_limit(4, 4);
 let rt = builer.build();
 let _ = rt.spawn(async move {});
