Configuration with rust analyzer

[jackpeters667]

Hi there. Thanks for the plugin.
How would I attach this completion engine to rust analyzer's LSP?

You need to install additional source for nvim-lsp

I think my question is how to attach the source to nvim-cmp because I have nvim-lsp installed. I tried listing nvim-lsp under sources but no dice. Tried rust-analyzer second, nothing also.
If you get a gap, please have a look and let me know how I should modify the config. I attached my pastebin link.

lang.vim

Instead of the server name, you should use the source name

sources = {
      { name = 'buffer' },
      { name = 'nvim_lsp' },
    },

Awesome. I'm getting completions now, auto imports aren't working though.
Is there something else I need to check?

Did you set up the cmp-nvim-lsp's README.md?

Yeah, I did.
Line 61 here

Is that it?

auto-import is works in my environment. I can't repro

Ah. Your config has no mapping option.

[jackpeters667]

Was about to ask for your mapping lol. Could you share please?

[hrsh7th]

Please read README.md https://github.com/hrsh7th/nvim-cmp#readme

[jackpeters667]

Yeah I had that before but I got some errors,

Error executing lua [string ":lua"]:30: attempt to call field 'prev_item' (a nil value)

So I moved it out and tried to use inoremap, which wouldn't work

[hrsh7th]

Please update plugin and set mapping oprion.

Ahh all good now. Thanks buddy
