Function List languages have gone missing

[gabenodarse]

Description of the Issue

Languages which used to have their functions appear in the Function List have gone missing, or at least Rust no longer has support for navigating to functions via Function List

Steps to Reproduce the Issue

1. Open up or create a file with .rs extension
2. Make sure that a correctly defined function is in the file
3. Save the file
4. Observe that the function does not show up on the Function List

Other info

I am certain that Rust used to be supported. A Rust file I've been working on no longer has its function's appear. I believe that the version I was using before was 7.9.1.

See #9592.
There is no support for autocompletion and functionlist for rust.
Rust is autodetected for extension '.rs' . Could you check which programming language is detected for your rust file.

What is possible is to switch to a similar language like C or C++ and then have the functionlist, but then also the other lexer is used and the syntax highlighting is not accurate.

Maybe you also did some own modification for rust which are overwritten/deleted by the update.

I checked and the language is being set correctly to Rust for the .rs extension. Thanks for the idea for using C/C++ for function list, but syntax highlighting is not something I'm willing to give up.

I did have a custom Rust function list extension I made for myself at some point when I was less busy. Maybe I'll try setting it up again.

Try portable version, if works you have some old config file (probably langs.xml).

Thank you for the help. I'll just try creating a quick usable parser for rust functions.

@gnodarse See PR#9727, with a first simple version, which you might want to extend. Maybe you could also check the corresponding unittest file for missing rust syntax examples. Just added some from https://doc.rust-lang.org/reference/items/functions.html.
