Welcome to The Rust Edition Guide! “Editions” are Rust’s way of introducing changes into the language that would not otherwise be backwards compatible.
This book explains the concept of 'editions', major new eras in Rust's development.
In this guide, we’ll discuss:
- What editions are
- Which changes are contained in each edition
- How to migrate your code from one edition to another
Async-graphql is a GraphQL server-side library implemented in Rust. It is fully compatible with the GraphQL specification and most of its extensions, and offers type safety and high performance.
You can define a Schema in Rust and procedural macros will automatically generate code for a GraphQL query. This library does not extend Rust’s syntax, which means that Rustfmt can be used normally. I value this highly and it is one of the reasons why I developed Async-graphql.
Juniper is a GraphQL server library for Rust. Build type-safe and fast API servers with minimal boilerplate and configuration.
GraphQL is a data query language developed by Facebook intended to serve mobile and web application frontends.
Juniper makes it possible to write GraphQL servers in Rust that are type-safe and blazingly fast. We also try to make declaring and resolving GraphQL schemas as convenient as possible as Rust will allow.
Juniper does not include a web server - instead it provides building blocks to make integration with existing servers straightforward. It optionally provides a pre-built integration for the Hyper, Iron, Rocket, and Warp frameworks, including embedded Graphiql for easy debugging.
Juniper supports the full GraphQL query language according to the specification (October 2021), including interfaces, unions, schema introspection, and validations. It does not, however, support the schema language.
As an exception to other GraphQL libraries for other languages, Juniper builds non-null types by default. A field of type Vec\<Episode\> will be converted into \[Episode!\]!. The corresponding Rust type for e.g. \[Episode\] would be Option\<Vec\<Option\<Episode\>\>\>.
The Rustonomicon is your guidebook to the dark arts of unsafe Rust. It’s also sometimes called “the ’nomicon.”
The Rustonomicon digs into all the awful details that you need to understand when writing Unsafe Rust programs.
Should you wish a long and happy career of writing Rust programs, you should turn back now and forget you ever saw this book. It is not necessary. However if you intend to write unsafe code — or just want to dig into the guts of the language — this book contains lots of useful information.
Unlike The Rust Programming Language, we will be assuming considerable prior knowledge. In particular, you should be comfortable with basic systems programming and Rust. If you don’t feel comfortable with these topics, you should consider reading The Book first. That said, we won’t assume you have read it, and we will take care to occasionally give a refresher on the basics where appropriate. You can skip straight to this book if you want; just know that we won’t be explaining everything from the ground up.
This book exists primarily as a high-level companion to The Reference. Where The Reference exists to detail the syntax and semantics of every part of the language, The Rustonomicon exists to describe how to use those pieces together, and the issues that you will have in doing so.
Cargo is the [Rust](https://rust-lang.niqin.com/en-us)'s *[package manager](https://cargo-book.niqin.com/en-us/appendix/glossary.html#package-manager '"package manager" (glossary entry)')*. Cargo downloads your Rust [package](https://cargo-book.niqin.com/en-us/appendix/glossary.html#package '"package" (glossary entry)')’s dependencies, compiles your packages, makes distributable packages, and uploads them to [crates.io](https://crates.io/), the Rust community’s *[package registry](https://cargo-book.niqin.com/en-us/appendix/glossary.html#package-registry '"package registry" (glossary entry)')*.
A book on Rust’s package manager and build system.
Learn how to make awesome documentation for your crate.
The Reference is not a formal spec, but is more detailed and comprehensive than the book.
This book is the primary reference for the Rust programming language. It provides three kinds of material:
- Chapters that informally describe each language construct and their use.
- Chapters that informally describe the memory model, concurrency model, runtime services, linkage model, and debugging facilities.
- Appendix chapters providing rationale and references to languages that influenced the design.
- This book is incomplete. Documenting everything takes a while.
- This document is not normative. It may include details that are specific to rustc itself, and should not be taken as a specification for the Rust language. We intend to produce such a document someday, but this is what we have for now.
This *Rust Cookbook*:
* Is a collection of simple examples;
* That demonstrate good practices to accomplish common programming tasks, using the crates of the Rust ecosystem.

Rust is a modern systems programming language focusing on safety, speed, and concurrency. It accomplishes these goals by being memory safe without using garbage collection.
Rust by Example (RBE) is a collection of runnable examples that illustrate various Rust concepts and standard libraries. To get even more out of these examples, don't forget to install Rust locally and check out the official docs. Additionally for the curious, you can also check out the source code for this site.

Rhai is an embedded scripting language and evaluation engine for Rust that gives a safe and easy way
to add scripting to any application.
Targets and builds
* All CPU and O/S targets supported by Rust, including:
* WebAssembly (WASM)
* Minimum Rust version 1.57
* Fairly efficient evaluation (1 million iterations in 0.3 sec on a single-core, 2.3 GHz Linux VM).
* Tight integration with native Rust functions and types, including getters/setters, methods and indexers.
* Freely pass Rust values into a script as variables/constants via an external Scope - all clonable Rust types are supported; no need to implement any special trait. Or tap directly into the variable resolution process.
* Built-in support for most common data types including booleans, integers, floating-point numbers (including Decimal), strings, Unicode characters, arrays (including packed byte arrays) and object maps.
* Easily call a script-defined function from Rust.
* Relatively little unsafe code (yes there are some for performance reasons).
* Few dependencies - currently only smallvec, num-traits, ahash, bitflags and smartstring.
* Re-entrant scripting engine can be made Send + Sync (via the sync feature).
* Compile once to AST form for repeated evaluations.
* Scripts are optimized (useful for template-based machine-generated scripts).
* Easy custom API development via plugins system powered by procedural macros.
* Function overloading and operator overloading.
* Dynamic dispatch via function pointers with additional support for currying.
* Closures (anonymous functions) that can capture shared values.
* Some syntactic support for object-oriented programming (OOP).
* Organize code base with dynamically-loadable modules, optionally overriding the resolution process.
* Serialization/deserialization support via serde (requires the serde feature).
* Support for minimal builds by excluding unneeded language features.
* A debugging interface.
Protected against attacks
* Don't Panic guarantee - Any panic is a bug. Rhai subscribes to the motto that a library should never panic the host system, and is coded with this in mind.
* Sand-boxed - the scripting engine, if declared immutable, cannot mutate the containing environment unless explicitly permitted.
* Rugged - protected against malicious attacks (such as stack-overflow, over-sized data, and runaway scripts etc.) that may come from untrusted third-party user-land scripts.
* Track script evaluation progress and manually terminate a script run.
* Passes Miri.
For those who actually want their own language
* Use as a DSL.
* Disable certain language features such as looping.
* Further restrict the language by surgically disabling keywords and operators.
* Define custom operators.
* Extend the language with custom syntax.
It wasn’t always so clear, but the Rust programming language is fundamentally about empowerment: no matter what kind of code you are writing now, Rust empowers you to reach farther, to program with confidence in a wider variety of domains than you did before.
Take, for example, “systems-level” work that deals with low-level details of memory management, data representation, and concurrency. Traditionally, this realm of programming is seen as arcane, accessible only to a select few who have devoted the necessary years learning to avoid its infamous pitfalls. And even those who practice it do so with caution, lest their code be open to exploits, crashes, or corruption.
Rust breaks down these barriers by eliminating the old pitfalls and providing a friendly, polished set of tools to help you along the way. Programmers who need to “dip down” into lower-level control can do so with Rust, without taking on the customary risk of crashes or security holes, and without having to learn the fine points of a fickle toolchain. Better yet, the language is designed to guide you naturally towards reliable code that is efficient in terms of speed and memory usage.
Programmers who are already working with low-level code can use Rust to raise their ambitions. For example, introducing parallelism in Rust is a relatively low-risk operation: the compiler will catch the classical mistakes for you. And you can tackle more aggressive optimizations in your code with the confidence that you won’t accidentally introduce crashes or vulnerabilities.
But Rust isn’t limited to low-level systems programming. It’s expressive and ergonomic enough to make CLI apps, web servers, and many other kinds of code quite pleasant to write — you’ll find simple examples of both later in the book. Working with Rust allows you to build skills that transfer from one domain to another; you can learn Rust by writing a web app, then apply those same skills to target your Raspberry Pi.
This book fully embraces the potential of Rust to empower its users. It’s a friendly and approachable text intended to help you level up not just your knowledge of Rust, but also your reach and confidence as a programmer in general. So dive in, get ready to learn—and welcome to the Rust community!
