Clippy VS Rustlings

cargo, rustfmt, clippy, rust-analyzer, and Rust’s robust unit testing capabilities together form a powerful ecosystem for managing large-scale projects like Spin.

Firstly, I added a section to run the code formatter rustfmt and the linter clippy:

I couldn't find it in the API guidelines either. From what I understand, the idea is that any trait bounds, which includes generic type parameter bounds and lifetime bound on a type (struct or enum) would be repeated back in the impl block

there is a nice discussion on this issue here: https://github.com/rust-lang/rust-clippy/issues/1689

You should not blindly follow clippy lints. They are sometimes wrong. Another example https://github.com/rust-lang/rust-clippy/issues/9782 .

I often write () = f() to assert that f() is unit. Unfortunately clippy warns on such code ( https://github.com/rust-lang/rust-clippy/issues/9048 ). There are very recent pull requests for this bug, so hopefully this bug will be fixed very soon. But meanwhile I invented this workaround: [()] = [f()] :)

Apart from running clippy on many projects being essential, clippy is also an exceptionally welcoming project, no matter your prior knowledge.

clippy is a great place to get started :) though it isn't exactly new.

clippy is also pretty compiler-adjacent and unlike rust-analyzer uses rustc's internal APIs. Don't let the size of the code base scare you off! It's actually feasible for a newcomer to contribute even such a substantial change as a new lint, and we have issues labeled as "good first issue" that come with mentorship, so you don't need to go it alone.

Yes, you could use it to write a lint. Although you might find it easier to just fork Clippy and add your own lints to their existing framework.

I think that's how it all started: https://github.com/rust-lang/rustlings

Rustlings - Small exercises to get you used to reading and writing Rust code

Recently I got this obsession to learn Rust. While there are plenty of documentation around, like Rust Book, some good published books, tutorials, rustling, I always struggle to learn something when I am not doing something practical, so I have decided to go to my comfort zone and write a Kubernetes Controller using kube-rs.

Finish again the rustlings.

I’ve been meaning to do this for years, and just played around with rust a bit (liked it, but the wrappers around some c++ stuff i wanted to use were half baked). Learning rust, there was this “rustlings” thing [0] that was a set of guided exercises to go alongside the rust book. Fastest I’ve ever picked up a language, thanks to that. Do you or anyone know anything similar for c++?

Rustlings

It is becoming more and more applicapible to the Web... Servers and clients with #wasm, you can actually natively import a rust module into node.js for extra threads or heavy lifting. Start learning!

Practice with "Rust by Example" and "Rustlings"

Surprised no one has mentioned another great and similar resource called Rustlings [0] (yes very punny name). You are given some files with todo statements which you'll need to fix and make the code compile and pass all the tests. It's an interactive way to learn which is what got me through learning Rust a few years ago.
