Rustup
If you use rustup, the recommended way to install and update Rust, then the docs may already be installed; the default installation behavior has changed over time. Try running rustup doc
to open them in your browser.
If they aren't already installed, you can download the docs by running rustup component add rust-docs
.
By default, rustup doc
opens the documentation front page, but you can add --std
to jump straight to the standard API docs or --book
for The Rust Programming Language. You can also use rustup doc std::iter::Iterator
to open the documentation of a specific item.
rustup 1.20 learned the concept of profiles. These allow you to default to having docs installed for a toolchain (via the default
profile) or not (via the minimal
profile).
Standalone Rust Installer
The Rust installer also installs the documentation for the language and for Cargo. On Linux systems, it can be found at /usr/local/share/doc/{rust,cargo}
.
