Rustlings VS rust.vim

So here's the story. I decided to learn Rust, read the docs, solved the rustlings challenges. The next step in learning a new programming language is to build something with it. And so began my dilemma.

I'm learning Rust and solving the rustlings exercises.

Rustlings is a CLI-based open source project of small challenges that help to grow your knowledge of the language.

i can't truly speak to the relative steepness, i think like both rust and c++ can get quite steep depending on what you're doing but can also be simple in other cases. best to just try it out i'd say :) the rustlings guide https://github.com/rust-lang/rustlings which parallels the rust book https://doc.rust-lang.org/book/ is a good way to learn. doing things like advent of code could also help. the most common hurdles with rust are "lifetimes" and "the borrow checker", and it just takes practice to figure them out

I recommend checking out the Rustlings exercises - they provide a really good overview of approaching concepts in Rust, if you're having difficulty with the docs.

perfect thank you so much for the explanation and for the link i got it working :)

Working through the rustlings exercises

The book is great and was my original introduction to the language, but rustlings or Rust By Example might be more interesting for an interactive (and more self paced) approach.

Rustlings: This is a great resource for getting started with Rust, with small exercises to help you get comfortable reading and writing code.

Coworker was getting syntax error without saving because of using https://github.com/rust-lang/rust.vim and not from lsp/rust-analyzer

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 It might be the built-in Rust support is out of date -- using that repo as a plugin would do the trick.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.

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

It seems, https://github.com/rust-lang/rust.vim already covers all that. Does your solution provide any advantage over the plugin?

Funny you should mention it, I wrote a complete syntax file for Rust with regex and didn't have much trouble with it. I personally think the :syntax API is awesome.

For other Vimmers on here who like using the quickfix list instead, as long as you have makeprg set (I use https://github.com/rust-lang/rust.vim and I believe it auto-sets that), you can just run:
