The Rust Bookshelf
, each book is different.
As Rust's documentation has grown, we've gained far more than just "The book" and the reference. We now have a collection of various long-form docs, nicknamed "the Rust Bookshelf." Different resources are added at various times, and we're adding new ones as more get written.
The Cargo book
Historically, Cargo’s docs were hosted on http://doc.crates.io, which doesn’t follow the release train model, even though Cargo itself does. This led to situations where a feature would land in Cargo nightly, the docs would be updated, and then for up to twelve weeks, users would think that it should work, but it wouldn’t yet. https://doc.rust-lang.org/cargo is the new home of Cargo’s docs, and http://doc.crates.io now redirects there.
The rustdoc
book
Rustdoc, our documentation tool, now has a guide at https://doc.rust-lang.org/rustdoc.
Rust By Example
Rust by Example used to live at https://rustbyexample.com, but now is part of the Bookshelf! It can be found at https://doc.rust-lang.org/rust-by-example/. RBE lets you learn Rust through short code examples and exercises, as opposed to the lengthy prose of The Book.
