rustbot added the needs-triage label Jun 12, 2024 compiler-errors self-assigned this Jun 12, 2024 Member compiler-errors commented Jun 12, 2024 actually this has nothing to do with async closures this is one of many issues having to do with async, higher ranked bounds, and Send/Sync...
在Rust 当中闭包(closures)算是装有捕获数据的语法糖, 外加一个某个Fn traits 的实现, 以便能够被调用.Generators 和这差不多, 除了它们也实现了 Generator trait [注释4]. 通常generator会保存一个 enum 来表示不同的状态. Unstable book 这本在线书里有些例子, 来展示 generat...
This function is a direct translation of theexamplefunction fromabovethat used combinator functions. Using the.awaitoperator, we can retrieve the value of a future without needing any closures orEithertypes. As a result, we can write our code like we write normal synchronous code, with the diff...
Crust of Rust 系列之 - functions, closures and their traits Jonhoo 的 Crust of Rust 系列是不可多得的 rust 进阶资料。在这个视频中,他非常详细地说明了函数,函数指针,闭包之间的区别,以及它们如何作用于 Fn* trait,同时提到了 Fn 类型如何处理动态派发。
But once we have async closures this will become possible to express. Pretty much all differences between std and async-std are minor issues like these, which we're fairly certain can be solved once Async Rust gains more capabilities. ←...
async/.await是一种特殊的Rust语法,它使您能够产生对当前线程的控制,而不是阻塞,从而允许其他代码在等待操作完成时取得进展。 There are two main ways to use async: async fn and async blocks. Each returns a value that implements the Future trait: 使用async有两种主要方法:async fn和async块。每个函数都...
Async closures. We would like to support the obvious async || syntax that would generate a closure. This may require tinkering with the Fn trait hierarchy. How you can get involved There’s been a lot of great work on the async fn implementation since my first post – we’ve closed over...
Concrete async closures themselves, e.g. async || (), would still, when called, return some type that implements both Future and IntoFuture. This is what @compiler-errors put up in the PR rust-lang/rust#127225 for discussion. The rationale for this would be that, in the case of concr...
Please read [RFC 3668](https://rust-lang.github.io/rfcs/3668-async-closures.html) to understand the general motivation of the feature. This is a very technical and somewhat "vertical" chapter; ideally we'd split this and sprinkle it across all the relevant chapters, but for the purposes ...
