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
minimalprofile when installing a Rust toolchain, Clippy is not automatically installed.
If Clippy was not installed for a toolchain, it can be installed with
$ rustup component add clippy [--toolchain=<name>]
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.
