I can install rustup, use cargo and rustfmt on my Raspberry PI. It's nice to be able to learn Rust on a platform made to learn computing.
Now clippy is described by the community, and official blogs, as an experienced Rustacean helping you write more idiomatic rust code. It would be nice to be able to use it on a PI.

$ rustup component add clippy
