External learning resources
The Rust programming language community also hosts a number of other texts and resources relating to advanced concepts or domain applications.
The Rust ReferenceEdit
The Rust Reference is the primary text for what is considered stable Rust. It is by no means a formal specification of Rust, but it contains most things you need to know about it.
The Rustlings CourseEdit
The Rustlings Course is a community-maintained course that contains "small exercises to get you used to reading and writing Rust code". This course is terminal-based, although there is an (older) web-based version that provides links exercises in the Rust Playground.
The Rustonomicon (often abbreviated to just the "nomicon") is an online community-reviewed text concerning or related to unsafe code in the Rust programming language.As stated by the documentation itself:
Topics that are within the scope of this book include: the meaning of (un)safety, unsafe primitives provided by the language and standard library, techniques for creating safe abstractions with those unsafe primitives, subtyping and variance, exception-safety (panic/unwind-safety), working with uninitialized memory, type punning, concurrency, interoperating with other languages (FFI), optimization tricks, how constructs lower to compiler/OS/hardware primitives, how to not make the memory model people angry, how you're going to make the memory model people angry, and more.
Rust by ExampleEdit
Rust by example is a collection of runnable code examples and exercises to help better understand certain language features.
Tour of RustEdit
Tour of Rust is a Rust tutorial available in several languages. It includes code examples that can be modified and executed in the browser.
Learn Rust with Entirely Too Many Linked ListsEdit
Learn Rust with Entirely Too Many Linked Lists is a book tutorial that implements six linked lists in Rust. It uses unsafe frequently, as linked lists are difficult to implement safely.
Exercism, a free platform to practice programming skills with exercises and feedback from mentors, has a Rust track with over 90 exercises.
Books by the Working GroupsEdit
The following books are written by Rust's Working Groups and are available for free online.
Command Line BookEdit
The Command Line Book teaches how to write command-line interface (CLI) applications in Rust. It is currently outdated, since it uses deprecated crates.
The WebAssembly Book teaches how to write and distribute WebAssembly (WASM) modules in Rust, and how to interoperate with browser APIs.
The Embedded Book teaches how to use Rust on "Bare Metal" embedded systems, such as microcontrollers.
The Async Book teaches how to develop asynchronous programs in Rust.
