Rust Standard Library Cookbook

By: Jan Hohenheim, Daniel Durante

Overview of this book

Mozilla’s Rust is gaining much attention with amazing features and a powerful library. This book will take you through varied recipes to teach you how to leverage the Standard library to implement efficient solutions. The book begins with a brief look at the basic modules of the Standard library and collections. From here, the recipes will cover packages that support file/directory handling and interaction through parsing. You will learn about packages related to advanced data structures, error handling, and networking. You will also learn to work with futures and experimental nightly features. The book also covers the most relevant external crates in Rust. By the end of the book, you will be proficient at using the Rust Standard library.

How to do it...

  1. Inside the bin folder, create a new file called
  2. Add the following code and run it with cargo run --bin oneshot:
1   extern crate futures;
3   use futures::prelude::*;
4   use futures::channel::oneshot::*;
5   use futures::executor::block_on;
6   use futures::future::poll_fn;
7   use futures::stream::futures_ordered;
9   const FINISHED: Result<Async<()>, Never> =
Ok(Async::Ready(())); 10 11 fn send_example() { 12 // First, we'll need to initiate some oneshot channels like
so: 13 let (tx_1, rx_1) = channel::(); 14 let (tx_2, rx_2) = channel::(); 15 let (tx_3, rx_3) = channel::(); 16 17 // We can decide if we want to sort our futures by FIFO
(futures_ordered) 18 // or if the order doesn't matter (futures_unordered) 19 // Note: All futured_ordered()'ed futures must be set as a
