How should I use RustFmt to format my file?

[Catizard]

Hi, I'm just migrating from rust-tools to here, and I don't know how to use 'RustFmt'. Since when I typed it in a regular rs file and it shows me a pager screen which content is just the same file, and at the bottom it says

Error detected while processing function rustfmt#Format[7]..<SNR>49_RunRustfmt:                                                               
line   48:

Press ENTER or type command to continue  

Maybe I have a broken config, but I really don't know what's happening and how to solve this.
I tried searching at document and discussions and found nothing, so I opened this.

Hey 👋

I think you've got the wrong plugin. This plugin doesn't define a RustFmt command.
rust.vim does.

To format your file with the LSP client started by this plugin, you can run

:lua vim.lsp.buf.format { async = true }

I'd recommend a keymap:

vim.keymap.set({ 'n', 'v' }, '<space>f', function()
    vim.lsp.buf.format { async = true }
end, desc('[lsp] format buffer'))

which will format the entire buffer in normal mode, or just the visual selection in visual mode.

Thank you for your reply.
I checked directly call vim.lsp.buf. format and it works fine.
Original problem might be some strange default behaviour of astronvim, sorry for this

Man... this blew my mind. I started making an issue how RustFmt wasnt honoring nightly and I found this issue, and found out this isnt even a part of rustacean. its just a part of default nvim 🤯 it says its the rust filetype plugin.... when i look at the location of the docs for this, its just installed with nvim it seems.

I found another issue I think on how to enable nightly stuff
