lazy.nvim not loading rustaceanvim

[rhaskia]

I've just set up rustaceanvim with lazy as shown in the readme, but it does not seem to load, and syntax highlighting takes a good few seconds to show up. I'm just wondering if I may have missed something that I need to set up for it to work.

Hey 👋

rustaceanvim doesn't do any syntax highlighting - that would probably be nvim-treesitter.

This plugin doesn't load anything at startup - only when you open a rust file.
You can see if all the requirements are met by running :checkhealth rustaceanvim.

🤔 That shouldn't necessary though.
Afaik, the ft = { 'rust' }, option tells lazy.nvim to load the plugin when a rust file is opened.

Either there's a bug in the lazy.nvim version you're using, or there's another setting somewhere disabling that (I don't use lazy.nvim myself so I'm afraid I can't really help with that).

Either way, lazy loading this plugin doesn't save you any startup time.

yeah, it's confusing me too, I only just installed lazy a few days ago just for this plugin. weirdly enough, even after forcing the plugin to activate syntax highlighting only shows properly on the main.rs file

syntax highlighting only shows properly on the main.rs file

That could be caused by an error, which prevented the syntax highlighting from being enabled.
You could try and reproduce it and run :messages to see if there are any error messages not being displayed.

Ah, managed to fix all the problems by removing the config I had in ~/.config/nvim/after/ftplugin/rust.lua. I think something may have broken the file type loading from that. Thank you for all the help though!

Wow! I spend a day on this!
I removed:
~/.config/nvim/ftplugin/rust.lua.
And it worked!
