Learn how to use futures by building them from scratch. Part 2 focuses on Tokio Internals: Understanding Rust's asynchronous I/O framework from the The Future trait from futures represents an asynchronous operation that can fail or 26 Mar 2019 hyper · rust13 points · 11 months ago. Looks great, one note: the first Future which yields not ready if count isn't high enough is missing a way to notify the task 3 Dec 2018 The trickiest bit for me when first learning for_each was to realize that, like and_then , it needs to end with a Future . I don't know if that was just my 2 May 2019 If you are consuming Futures (for example when a crate you are using is returning a Future ), you have to understand where the data comes from.

How can you understand causality when you don't know when a function is going to be This allows Tokio to interop with other libraries also using the futures crate. To gain this understanding, we'll first look at the synchronous model that Rust uses 5 Feb 2019 For example, future research in building Rust bug detectors should focus on unsafe code and atomic operations in safe code. Our findings and im 5 Jul 2017 use futures::{Future, Poll, Async};. A future in rust is an implementation of the trait “Future”. “Poll” is basically a type for a Result Rust is a systems programming language meant to replace a lot of C and C++ Understand quality-driven development with best practices from QA 20 Aug 2019 Rust's Future trait is often considered to be difficult to understand, not because it is complex but because it is something that people are not Learn about the expiration and rollover of futures contract and what your choices are when the lifespan of a contract comes to an end. 15 Oct 2019 I'd love to know what the community thinks of this, what their pet peeves and pet features would be, and how they think this would help or hinder What makes Futures in rust so powerful is the suite of useful combinators available to chain computations, and asynchronous calls. We've learned about about Rust's powerful function pointer traits, FnOnce, FnMut, and Fn. We've learned how to work with the result type when it's embedded in a future. Futures in rust allow you to define a task, like a network call or computation, to be run asynchronously. You can chain functions onto that result, transform it, handle errors, merge it with other futures, and perform many other computations on it. Those will only be run when the future is passed to an executor like the tokio library's run function. In fact, if you don't use a future before it falls out of scope, nothing will happen. For this reason the futures crate declares futures 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. 26 Mar 2019 hyper · rust13 points · 11 months ago.
