Text of the page (random words):
rust documentation rust documentation welcome to an overview of the documentation provided by the rust project this page contains links to various helpful references most of which are available offline if opened with rustup doc many of these resources take the form of books we collectively call these the rust bookshelf some are large some are small all of these books are managed by the rust organization but other unofficial documentation resources are included here as well if you re just looking for the standard library reference here it is rust api documentation learning rust if you d like to learn rust this is the section for you all of these resources assume that you have programmed before but not in any specific language the rust programming language affectionately nicknamed the book the rust programming language will give you an overview of the language from first principles you ll build a few projects along the way and by the end you ll have a solid grasp of how to use the language rust by example if reading multiple hundreds of pages about a language isn t your style then rust by example has you covered rbe shows off a bunch of code without using a lot of words it also includes exercises rustlings rustlings guides you through downloading and setting up the rust toolchain then provides an interactive tool that teaches you how to solve coding challenges in rust rust playground the rust playground is a great place to try out and share small bits of code or experiment with some of the most popular crates using rust once you ve gotten familiar with the language these resources can help you put it to work the standard library rust s standard library has extensive api documentation with explanations of how to use various things as well as example code for accomplishing various tasks code examples have a run button on hover that opens the sample in the playground search your personal documentation whenever you are working in a crate cargo doc open will generate documentation for your project and all its dependencies in their correct version and open it in your browser add the flag document private items to also show items not marked pub rust version history the release notes describes the change history of the rust toolchain and language the edition guide describes the rust editions and their differences the latest version of the toolchain supports all historical editions the rustc book the rustc book describes the rust compiler rustc the cargo book the cargo book is a guide to cargo rust s build tool and dependency manager the rustdoc book the rustdoc book describes our documentation tool rustdoc the clippy book the clippy book describes our static analyzer clippy extended error listing many of rust s errors come with error codes and you can request extended diagnostics from the compiler on those errors with rustc explain you can also read them here if you prefer rustc error codes mastering rust once you re quite familiar with the language you may find these advanced resources useful the reference the reference is not a formal spec but is more detailed and comprehensive than the book the style guide the rust style guide describes the standard formatting of rust code most developers use cargo fmt to invoke rustfmt and format the code automatically the result matches this style guide the rustonomicon the rustonomicon is your guidebook to the dark arts of unsafe rust it s also sometimes called the nomicon the unstable book the unstable book has documentation for unstable features the rustc development guide the rustc dev guide documents how the compiler works and how to contribute to it this is useful if you want to build or modify the rust compiler from source e g to target something non standard specialized rust when using rust in specific domains consider using the following resources tailored to each area embedded systems when developing for bare metal or embedded linux systems you may find these resources maintained by the embedded working group useful the embedded rust book the embedded rust book is targeted at developers familiar with embedded development and familiar with rust but have not used rust for embedded development
