Clippy VS rust.vim

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.

I am using rustaceanvim and rust.vim.

When the file first loads, it uses the syntax defined in the $VIMRUNTIME/syntax/rust.vim file from rust.vim, which is what I want, but after a few seconds (probably once rust-analyzer loads and runs), it changes the highlighting to use different colours (there's probably a better way to describe it, but a video is easier to show). This colour change also happens when I write the file (and rust-analyzer runs again).

Or this https://github.com/rust-lang/rust.vim, it has example with running tests

If you need basic syntax checking on leaving insert mode (without saving file), https://github.com/rust-lang/rust.vim can be used

Seems like there's a tree-sitter solution, but I do want to note that this works out of the box with rust.vim: https://github.com/rust-lang/rust.vim/issues/63. It might be the built-in Rust support is out of date -- using that repo as a plugin would do the trick.

Most of the customizations in the $VIMRUNTIME's rust ftplugin are guarded behind a flag (g:rust_fold, g:rustfmt_autosave,g:rust_recommended_style, etc.) to control enabling and disabling them, but for some reason the navigation mappings are unconditionally defined, with no flag to turn them off... It might be worth going through the issues in https://github.com/rust-lang/rust.vim to see if that ever came up before.

Is having rust.vim necessary if I'm using rust-tools already?

Primeagen has a series, you could also try spacevim or lunarvim( i prefer lunarvim). If you want to read the docs and setup yourself 1. lsp and code completion mentioned in #5. 2. treesitter 3. lsp handles that, you have to install java's lsp, this improves its look. 4. Make your own remaps, some languages have a plugin for this but i can't find one for java, this is the one for rust. 5. Install cmp and one of the snippet engines.

writing rust is the same regardless of which editor you use and using vim is the same regardless of what programming language you are in, so i dont think you need a tutorial neccissarily. ive been using this plugin for rust-specific features https://github.com/rust-lang/rust.vim

As for plugins for Rust development, I’d recommend Conquer of Completion (using the coc-rust-analyser coc plugin), Rust lang’s rust plugin, and the Toml plugin
