by Steve Klabnik, Carol Nichols, and Chris Krycho, with contributions from the Rust Community (and with experimental modifications!)

This version of the text assumes you’re using Rust 1.85.0 (released 2025-02-17) or later with edition = "2024" in the Cargo.toml file of all projects to configure them to use Rust 2024 edition idioms. See the “Installation” section of Chapter 1 to install or update Rust.

The experimental version is only available online and in English. The non-experimental version is available offline with installations of Rust made with rustup; run rustup doc --book to open.

Several community translations of the non-experimental version are also available. The non-experimental text is available in paperback and ebook format from No Starch Press.
