虽然Rust本身就支持Async编程,但很多应用依赖与社区的库: 标准库提供了最基本的特性、类型和功能,例如 Future trait async/await 语法直接被Rust编译器支持 futures crate 提供了许多实用类型、宏和函数。它们可以用于任何异步应用程序。 异步代码、IO 和任务生成的执行由 "async runtimes" 提供,例如 Tokio 和 async-...
Support for recursion inasync fn Async functions previously could not call themselves due to a compiler limitation. In 1.77, that limitation has been lifted, so recursive calls are permitted so long as they use some form of indirection to avoid an infinite size for the state of the function....
async Rust using real world patterns that show up consistently when creating non blocking, async, event loops, using channels. Delve into implementing the Future trait and async executor manually. Also explore graceful shutdown, when not to use async, and how to think about testing async code....

第二种是使用编译器推荐的crate,引入async_recursioncrate,可以隐藏复杂度。将代码改写为: useasync_recursion::async_recursion;fnmain(){}#[async_recursion]asyncfnrecursive(){recursive().await;recursive().await;} 写到这里有感,编写正确代码其实是非常困难的一件事,其中蕴含的复杂度是内在而故有的,无法被消...
recursion in an `async fn` requires boxing a recursive `async fn` must be rewritten to return a boxed `dyn Future` consider using the `async_recursion` crate: https://crates.io/crates/async_recursion 所以需要添加#[async_recursion]或者改成Box返回。 参数其中多定义了两组HashSet用来存储已处理的...
