Rust presents the authors of a book like this one with a challenge: what gives the language its character is not some specific, amazing feature that we can show off on the first page, but rather, the way all its parts are designed to work together smoothly in service of the goals we laid out in the last chapter: safe, performant systems programming. Each part of the language is best justified in the context of all the rest. So rather than tackle one language feature at a time, we’ve prepared a tour of a few small but complete programs, each of which introduces some more features of the language, in context: As a warm-up, we have a program that does a simple calculation on its command-line arguments, with unit tests. This shows Rust’s core types and introduces traits. Next, we build a web server. We’ll use a third-party library to handle the details of HTTP and introduce string handling, closures, and error handling. Our last program plots a beautiful fractal, distributing the computation across multiple threads for speed. This includes an example of a generic function, illustrates how to handle something like a buffer of pixels, and shows off Rust’s support for concurrency. Rust’s promise to prevent undefined behavior with minimal impact on performance influences the design of every part of the system, from the standard data structures like vectors and strings to the way Rust programs use third-party libraries. The details of how this is managed are covered throughout the book. But for now, we want to show you that Rust is a capable and pleasant language to use. First, of course, you need to install Rust on your computer.
