Disable ellipsis (…) unless snippets are expanded

[TheZoq2]

I'm aware that this might not be the correct place to ask this, but I'm also not sure if the source of my problem is rust-analyzer, LanguageClient-neovim or ncm2

My problem is best described by a video. Here I want to complete the append function so I start typing it, then do C-n to select it in the list. It inserts append(…) and when I press c-y which I have bound to ncm2_ultisnips#expand_or("\<CR>", 'n') it expands it with snippets.

However, I don't always want to have snippet expansion, for example if I want to add an append function on a line that already exists. Instead, I'd want c-n to comlete just append and the parens to not be added until I press c-y

Is this possible?

I tried setting rust-analyzer.completion.addCallParenthesis to false, but that seems to completely disable snippet completion

I think that comes as is from rust-analyzer, you can verify that if you set the logging level to INFO and check for the response message from the completion call. The label on that completion item includes the ellipsis. Might be worth asking in the rust-analyzer repo or zulip, maybe there's a way to have it not do that.
