Tips, tricks, design patterns, and secret features of Rust that will help you build stable and maintainable applications. Whether you’re a Rust beginner or a pro, Idiomatic Rust will teach you to be a better Rust programmer. It introduces essential design patterns for Rust software with detailed explanations, and code samples that encourage you to get stuck in. In Idiomatic Rust you’ll learn how to apply important design patterns including: • Fluent interfaces for creating delightful APIs • The Builder pattern to encapsulate data and perform initialization • Immutable data structures that help you avoid hard-to-debug data race conditions • Functional programming patterns • Anti-patterns and what not to do in Rust Idiomatic Rust catalogs, documents, and describes both how classic design patterns work with Rust, and the new Rust-specific patterns that will help you master the language. Each pattern or best practice helps solve common programming problems and ensure your code is easy for others to understand. You’ll learn when to use each pattern—and when to break it! You’ll soon be producing higher-quality Rust code and higher-quality Rust software. About the technology After you’re comfortable with Rust’s syntax and its uniquely-powerful compiler, there’s a whole new dimension to explore as you put it to use in real projects. How do you apply standard design patterns in Rust applications? Where and why should you use IntoIterator? Why do Rustaceans love the PhantomData type? This book answers these questions and many, many more. About the book Idiomatic Rust introduces the coding and design patterns you’ll need to take advantage of Rust’s unique language design. This book’s clear explanations and reusable code examples help you explore metaprogramming, build your own libraries, create fluent interfaces, and more. Along the way, you’ll learn how to write efficient, idiomatic Rust code that’s easy to maintain and evolve as you learn how the language works under the hood.

Master professional-level coding in Rust. For developers who’ve mastered the basics, this book is the next step on your way to professional-level programming in Rust. It covers everything you need to build and maintain larger code bases, write powerful and flexible applications and libraries, and confidently expand the scope and complexity of your projects. Author Jon Gjengset takes you deep into the Rust programming language, dissecting core topics like ownership, traits, concurrency, and unsafe code. You’ll explore key concepts like type layout and trait coherence, delve into the inner workings of concurrent programming and asynchrony with async/await, and take a tour of the world of no_std programming. Gjengset also provides expert guidance on API design, testing strategies, and error handling, and will help develop your understanding of foreign function interfaces, object safety, procedural macros, and much more. You'll Learn: How to design reliable, idiomatic, and ergonomic Rust programs based on best principles Effective use of declarative and procedural macros, and the difference between them How asynchrony works in Rust – all the way from the Pin and Waker types used in manual implementations of Futures, to how async/await saves you from thinking about most of those words What it means for code to be unsafe, and best practices for writing and interacting with unsafe functions and traits How to organize and configure more complex Rust projects so that they integrate nicely with the rest of the ecosystem How to write Rust code that can interoperate with non-Rust libraries and systems, or run in constrained and embedded environments Brimming with practical, pragmatic insights that you can immediately apply, Rust for Rustaceans helps you do more with Rust, while also teaching you its underlying mechanisms.

Rust is a new systems programming language that combines the performance and low-level control of C and C++ with memory safety and thread safety. Rust’s modern, flexible types ensure your program is free of null pointer dereferences, double frees, dangling pointers, and similar bugs, all at compile time, without runtime overhead. In multi-threaded code, Rust catches data races at compile time, making concurrency much easier to use. Written by two experienced systems programmers, this book explains how Rust manages to bridge the gap between performance and safety, and how you can take advantage of it. Topics include: How Rust represents values in memory (with diagrams) Complete explanations of ownership, moves, borrows, and lifetimes Cargo, rustdoc, unit tests, and how to publish your code on crates.io, Rust’s public package repository High-level features like generic code, closures, collections, and iterators that make Rust productive and flexible Concurrency in Rust: threads, mutexes, channels, and atomics, all much safer to use than in C or C++ Unsafe code, and how to preserve the integrity of ordinary code that uses it Extended examples illustrating how pieces of the language fit together

Rust's popularity is growing, due in part to features like memory safety, type safety, and thread safety. But these same elements can also make learning Rust a challenge, even for experienced programmers. This practical guide helps you make the transition to writing idiomatic Rust—while also making full use of Rust's type system, safety guarantees, and burgeoning ecosystem. If you're a software engineer who has experience with an existing compiled language, or if you've struggled to convert a basic understanding of Rust syntax into working programs, this book is for you. By focusing on the conceptual differences between Rust and other compiled languages, and by providing specific recommendations that programmers can easily follow, Effective Rust will soon have you writing fluent Rust, not just badly translated C++. Understand the structure of Rust's type system Learn Rust idioms for error handling, iteration, and more Discover how to work with Rust's crate ecosystem Use Rust's type system to express your design Win fights with the borrow checker Build a robust project that takes full advantage of the Rust tooling ecosystem

Learn Rust the Right Way! This book is a mini language reference on the Rust programming language. We go through all essential features of Rust 2021 Edition (and some newer language features) in this book. Rust is one of the most powerful languages, originally created for low-level systems programming. Rust is now widely used in other areas as well, such as Web application development. Rust is, in fact, one of the most popular/loved languages among developers. (And yet, it is one of the most difficult programming languages to learn.) This book is specifically written for * Experienced programmers who are new to Rust, or * Beginning Rust programmers who want to learn various fundamental concepts in Rust programming. That is, if you have some prior experience with Rust or other similar languages like C++ or Haskell, etc., then this book is for you. This book is, however, ultimately a "language reference", and it is not intended for complete beginners. The book covers * Rust crates. * Rust program items. * Names and variables. * Ownership and borrowing. * Blocks, scopes, lifetimes. * Types, traits, generics. * Special types, special traits. * Expressions. Statements. * Pattern matching. * Error handling. * Common macros. * Builtin attributes. Order your copy today and learn Rust the right way!
