Rust expToLua deprecation warning

[connor-grady]

I have confirmed that this is a bug related to nvf

• This is a bug, and not an user error or a support request. I understand that my issue will be closed if it is not a bug in nvf.
• I have checked the issues tab and confirmed that my issue has not yet been reported. I understand that my issue will be closed if it is a duplicate.

Description

I recently changed my Rust config and started getting deprecation warnings about expToLua, presumably due to this line:

nvf/modules/plugins/languages/rust.nix

Line 172 in 45aaf1c

then expToLua cfg.lsp.package

Looking at the git history, it seems like it was changed to toLuaObject in 3e48f13 and then changed back in 99b003f. Was this a mistake, or was there a reason for the change back?

Installation Method

NixOS Module (nixosModules.default)

Installation Method (Other)

No response

nvf Version

master

Reproduction steps

Set vim.languages.rust.lsp.package to any list of strings.

Expected behavior

Not receive deprecation warnings.

Actual Behavior

Received deprecation warnings.

Likely a merge artifact. I'll fix this if I can be on my system today.
