This repository contains the source of "The Rust Programming Language" book.

The book is available in dead-tree form from No Starch Press.

You can also read the book for free online. Please see the book as shipped with the latest stable, beta, or nightly Rust releases. Be aware that issues in those versions may have been fixed in this repository already, as those releases are updated less frequently.

See the releases to download just the code of all the code listings that appear in the book.

Building the book requires mdBook, ideally the same version that rust-lang/rust uses in this file. To get it:

$ cargo install mdbook --vers [version-num]

To build the book, type:

$ mdbook build

The output will be in the book subdirectory. To check it out, open it in your web browser.

Firefox:

$ firefox book/index.html                       # Linux
$ open -a "Firefox" book/index.html             # OS X
$ Start-Process "firefox.exe" .\book\index.html # Windows (PowerShell)
$ start firefox.exe .\book\index.html           # Windows (Cmd)

Chrome:

$ google-chrome book/index.html                 # Linux
$ open -a "Google Chrome" book/index.html       # OS X
$ Start-Process "chrome.exe" .\book\index.html  # Windows (PowerShell)
$ start chrome.exe .\book\index.html            # Windows (Cmd)

To run the tests:

$ mdbook test

We'd love your help! Please see CONTRIBUTING.md to learn about the kinds of contributions we're looking for.

We'd love help translating the book! See the Translations label to join in efforts that are currently in progress. Open a new issue to start working on a new language! We're waiting on mdbook support for multiple languages before we merge any in, but feel free to start!

To scan source files for spelling errors, you can use the spellcheck.sh script. It needs a dictionary of valid words, which is provided in dictionary.txt. If the script produces a false positive (say, you used word BTreeMap which the script considers invalid), you need to add this word to dictionary.txt (keep the sorted order for consistency).
