Rust Programming Cookbook

How it works...

Let's go through the code to understand the execution flow.

cargo is described in depth in Chapter 2, Managing Projects with Cargo, in this book.

The initial snippet is generated when cargo new hello-world is executed in step 1. As a project of type binary, a main function is required and rustc will be looking for it. Upon calling cargo run, cargo orchestrates compilation (with rustc) and linking (msvc on Windows, cc on *nix) and runs the resultant binary via its entry point: the main function (step 5).

In the function we create in step 3, we write a series of print!/println!/eprintln! statements, which are Rust macros. These macros facilitate the writing to the standard output or standard error channels of a command-line ...
