In most other places, poll_action means that 'action' is happening asynchronously. The name poll_cancel implies that the call will cancel the oneshot, but really we just wish to poll if it has been canceled. Today's OneShot is Rust! Rust is one of those games that's been around for ages and they just keep adding to it. It's a lot of fun with friends so today I'm I can't use select/select2 because then two futures will be running in a single thread. My current idea is to create two oneshot::channels: one for stopping the server and the other one for stopping the interval.

This modified text is an extract of the original Stack Overflow Documentation created by following contributors and released under CC BY-SA 3.0 Additionally as futures are composed using combinators such as map and join, we are actually building a more elaborate state machine, not manipulating the result of something that is already running somewhere. While this epiphany was very helpful in understanding how Futures operate in Rust, it still didn't explain the behavior I was seeing. Most of the stuff above still applies to the "new" features (but there are some differences like the Pin type) so it can be useful to read it, especially because combinators are still allowed.. That said, the await syntax is the future so you will have to study it anyway. You might as well start from there and save some time.
Sorry for bombarding with questions. Rust turned out not that intuitive to deal with futures. I have the the following source code sample. The first arm of the match in the call function collects the body in non-blocking way (I hope) and maps the result to the response. The second constructs the result of the future directly.

Attempt to filter the values produced by this stream according to the provided asynchronous closure. As values of this stream are made available, the provided predicate f will be run on them. If the predicate returns a Future which resolves to true, then the stream will yield the value, but if the predicate return a Future which resolves to false, then the value will be discarded and the next
Creates a new one-shot channel for sending values across asynchronous tasks. This function is similar to Rust's channel constructor found in the standard library. Two halves are returned, the first of which is a Sender handle, used to signal the end of a computation and provide its value. Zero-cost asynchronous programming in Rust. Contribute to rust-lang/futures-rs development by creating an account on GitHub. API documentation for the Rust `futures` crate. Async: Indicates whether a value is available, or if the current task has been scheduled for later wake-up instead. 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. Unlike select!, if multiple futures are ready, one will be selected in order of Trait for types which are a placeholder of a value that may become available at some later point in time. In addition to the documentation here you can also find more information about futures online at https://tokio.rs. Futures are used to provide a sentinel through which a value can be referenced.

28 Aug 2016 Personally, given that let (c, o) = oneshot::<()>(); only uses c and o once, there's no great need to shorten them so much. YMMV. Programming languages often use futures / promises to model asynchronous makes CompletableFuture (and similar types) one-shot futures by convention. 2016年12月31日 在前面我们简单的介绍了一些Futures 的基本知识的例子中，我们出现了combinator 的概念 学习Rust Futures - Concrete and Combinators futures 现在提供两种 channel，one-shot 以及MPSC。one-shot 主要用于两个线程之间 14 Dec 2016 You Only Have OneShot.

This is an attempt to reduce the amount of unsafe code and raw pointers in intrusive list usage. The main unsafe function is now adding a node to the intrusive linked list, which requires the caller to assure they will remove the item properly later on. Zero-cost asynchronous programming in Rust Documentation | Website futures-rs is a library providing the foundations for asynchronous programming in Rust. It includes key trait definitions like Stream, as well as utilities like join!, select!, and various futures combinator methods which enable expressive asynchronous control flow.. Usage.
