Rust Language Server VS Clippy

In the last there was RLS that did exactly that. But the approach of rust-analyzer was found to be more performant.

LSP support seems to be lacking as well, at least rust doesn't seem to have Cargo.toml support? https://github.com/rust-lang/rls/issues/785

apparently, it means that you're using the old RLS-based Rust plugin for VS Code, rather than the rust-analyzer plugin. You probably won't see a lot of people familiar with RLS's error messages.

Why: The rust-analyzer extension integrates with rust-analyzer, an alternative language server for Rust. rust-analyzer tends to perform better and get less confused with your code as compared to RLS, which the Rust extension uses.

I have tried writing websites with rust instead of JavaScript. Unfortunately, the tooling is just not there. More specifically, I am talking about wasm-bindgen, which provides two-way bindings. The problem with it is that since all the declarations are generated with build.rs, there is no autocompletion. Since I am spoiled by modern tooling, no autocompletion to me means not feasible pass demo stage. (https://github.com/rust-lang/rls/issues/1489)

Aside from the lack of autocompletion, passing rust closures to js land (DOM) is extremely janky as well. However, that might be caused by my lack of experience with rust.

(If you are curious, this is what I made: https://github.com/SCLeoX/non-grid-path-finder)

Python the core devs don't care about tooling and they have IDE's, Java is an enterprise monolith so IDE's are the standard, Rust yes it is (https://github.com/rust-lang/rls), Elm I have no idea I don't use it.

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.

Check out the readme for more information.

They are two of my favorite Rust tools. If you haven’t tried them yet, I highly recommend giving them a try. Clippy can detect various lints in your code and guide you towards writing more idiomatic code. To install Clippy, simply run rustup component add clippy, and to run it within your workspace, execute cargo clippy. For more details, visit Clippy’s GitHub repository.
