Rust Mini Reference

Book excerpt: 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!
