Rust Programming Cookbook

By: Claus Matzinger

Overview of this book

Rust 2018, Rust's first major milestone since version 1.0, brings more advancement in the Rust language. The Rust Programming Cookbook is a practical guide to help you overcome challenges when writing Rust code. This Rust book covers recipes for configuring Rust for different environments and architectural designs, and provides solutions to practical problems. It will also take you through Rust's core concepts, enabling you to create efficient, high-performance applications that use features such as zero-cost abstractions and improved memory management. As you progress, you'll delve into more advanced topics, including channels and actors, for building scalable, production-grade applications, and even get to grips with error handling, macros, and modularization to write maintainable code. You will then learn how to overcome common roadblocks when using Rust for systems programming, IoT, web development, and network programming. Finally, you'll discover what Rust 2018 has to offer for embedded programmers. By the end of the book, you'll have learned how to build fast and safe applications and services using Rust.

Starting subprocesses

Pipelines, container orchestration, and command-line tools all share a common task: they all have to start and monitor other programs. These system calls are done in a variety of ways in other technologies, so let's call a few standard programs with Rust's Command interface.

How to do it...

Follow these quick steps to call on external programs:

  1. Open a Terminal to create a new project using cargo new sub-processes. Use VS Code to open the project directory.
  2. Open src/main.rs. Rust's standard library comes with an external command interface built-in, but first, let's import it:
use std::error::Error;
use std::io::Write;
use std::process::{Command, Stdio};
  1. Once imported, we can do the...
