To really grasp the content of this book, it is recommended that you write out the example code and try fiddling with code to get familiar with the Rust's error messages, so they can guide you toward writing correct programs.

There isn't any specific hardware requirements for this book, and any system with a minimum of 1 GB of RAM and a fairly recent Linux operating system would be fine. All code examples and projects in this book were developed on a Linux machine running Ubuntu 16.04. Rust also offers first-class support for other OS platforms, including macOS, BSD, and recent versions of Windows, so all the code examples should compile and run fine on these platforms too.

You can download the example code files for this book from your account at www.packt.com. If you purchased this book elsewhere, you can visit www.packt.com/support and register to have the files emailed directly to you.

You can download the code files by following these steps:

1. Log in or register at www.packt.com.
2. Select the SUPPORT tab.
3. Click on Code Downloads & Errata.
4. Enter the name of the book in the Search box and follow the onscreen instructions.

Once the file is downloaded, please make sure that you unzip or extract the folder using the latest version of:

• WinRAR/7-Zip for Windows
• Zipeg/iZip/UnRarX for Mac
• 7-Zip/PeaZip for Linux

The code bundle for the book is also hosted on GitHub at https://github.com/PacktPublishing/Mastering-RUST-Second-Edition. In case there's an update to the code, it will be updated on the existing GitHub repository. Feel free to raise an issue on GitHub if you find any problems when compiling the code examples.

We also have other code bundles from our rich catalog of books and videos available at https://github.com/PacktPublishing/. Check them out!

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The project resides in a folder named threads_demo in the Chapter08/ directory."

A block of code is set as follows:

fn main() {
    println!("Hello Rust!");
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[dependencies]
serde = "1.0.8"
crossbeam = "0.6.0"
typenum = "1.10.0"

Any command-line input or output is written as follows:

$ rustc main.rs
$ cargo build

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
