If you're using rustup to install and manage you're Rust toolchains, Clippy is usually already installed. In that case you can skip this chapter and go to the Usage chapter.

Note: If you used the minimal profile when installing a Rust toolchain, Clippy is not automatically installed.

Using Rustup

If Clippy was not installed for a toolchain, it can be installed with

$ rustup component add clippy [--toolchain=<name>]

From Source

Take a look at the Basics chapter in the Clippy developer guide to find step by step instructions on how to build and install Clippy from source.
