Rust Programming Cookbook

Conventions used

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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

macro_rules! strange_patterns {    (The pattern must match precisely) => { "Text" };    (42) => { "Numeric" };    (;<=,<=;) => { "Alpha" };}

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

#[test]#[should_panic]fn test_failing_make_fn() {    make_fn!(fail, {assert!(false)});    fail(); } 

Any command-line ...
