API documentation for the Rust `Future` trait in crate `std`. Futures alone are inert; they must be actively polled to make progress, meaning that each time the current task is woken up, it should actively re-poll pending futures that it still has an interest in.

Futures directly passed to select! must be Unpin and implement FusedFuture. select_biased Polls multiple futures and streams simultaneously, executing the branch for the future that finishes first.

In computer science, future, promise, delay, and deferred refer to constructs used for For Rust: futures-rs. For Scala: Twitter's util library. For Swift: Async framework, implements C#-style async /non-blocking await; FutureKit, "Tutorial of Oz". The Future trait from futures represents an asynchronous operation that can fail or succeed, producing a value either way. It is like an async version of Result . This  You can find extensive tutorials and documentations at https://tokio.rs for both this crate (asynchronous programming in general) as well as the Tokio stack to  15 Apr 2019 Futures in Rust are analogous to promises in JavaScript. They are a powerful abstraction over the concurrency primitives available in Rust.

async /.await is Rust's built-in tool for writing asynchronous functions that look like synchronous code. async transforms a block of code into a state machine that implements a trait called Future.

API documentation for the Rust `Future` trait in crate `std`. Futures alone are inert; they must be actively polled to make progress, meaning that each time the current task is woken up, it should actively re-poll pending futures that it still has an interest in. Futures solve a very hard problem, but not everything is a very hard problem. Finding the line at which the ergonomic cost of Futures makes sense vs. not is key. This is why Tokio uses Futures as part of the Service trait: an inherently multi-threaded interface, but keeps them out of the event loop, which is inherently single threaded rust documentation: Futures and Async IO.

Intro. 如果你是一个程序员并且也喜欢Rust这门语言, 那么你应该经常在社区听到讨论Future 这个库的声音, 一些很优秀的Rust Crates都使用了Future 所以我们也应该对它有足够的了解并且使用它. Rust is an incredible language, but it goes beyond that. When I hear about a project in Rust, the authors seem to be in an idealistic frenzy, to create a better implementation that casts off the shackles of old. Even simple ports from c/c++ to rust invoke awe and enthusiasm, something I don't see even in seasoned veterans of other languages. RUST BASICS. This is the first post of Learning Rust series. Also now, you can read the same content via learning-rust.github.io 👈 . I think it’s more structured and easy to see the big picture.
