Add rust-analyzer.toml file

[alibektas]

Fixes #2104.

Just my amateur solution to this problem. Let me know if you have any stylistic changes you want me to make 👋

Thanks!

We don't need the small file in the repo. We can define the content in a &[u8] constant and use it like GITIGNORE:

rustlings/src/init.rs

Line 176 in 1f624d4

const GITIGNORE: &[u8] = b"Cargo.lock

I wonder if extraArgs will stay as is or get renamed to extra_args since camel case is common in TOML files.

I don't think a renaming is among our plans. In either case we never remove old config names and check for them too.

I just tested the config in a rust-analyzer.toml file with the Rust-Analyzer extention (pre-release from 09.12.) in VS-Code. It doesn't seem to work (yet?). See the screenshot where the function bigger is underlined. The warning is that this function isn't used. I restarted Rust-Analyzer after creating the config file and even restarted the whole editor. It doesn't seems to use that config.

That's odd. I made the warning go away when I tried it in my local. I will have another look at it in a few hours.

@alibektas Is .rust-analyzer.toml (with dot) also supported? It would be nice to be able to hide it from beginners.

not yet and we didn't really plan such thing but I can see people asking for it so I will implement it in a few days. I am making an issue of it an pinging you.
