Auto import has broken for vim-lsp

[only14vic]

rust-analyzer version: 1.85.1 (4eb1612 2025-03-15)

rustc version: 1.85.1 (4eb161250 2025-03-15)

editor or extension: vim 9.1.1198-1 + vim-lsp

After updating Rust from the old version 1.84.1 to the new 1.85.x autoimport has stopped adding the module path to the use section of file. At the same time, completion works fine.

If I switch to the old version of Rust 1.84.1 sh# rustup default 1.84 then autoimport works perfectly with the same vim-lsp settings.

I tried different values ​​in granularity.group and granularity.enforce but autoimport did not work.

vim-lsp settings:

au User lsp_setup call lsp#register_server({
    \   'name': 'rust-analyzer',
    \   'cmd': ['rust-analyzer'],
    \   'allowlist': ['rust'],
    \   'initialization_options': {
    \       'lens': { 'enable': v:false, 'debug': { 'enable': v:false } },
    \       'imports': {
    \           'preferPrelude': v:true,
    \           'preferNoStd': v:true,
    \           'granularity': {
    \               'group': 'one',
    \               'enforce': v:true
    \           }
    \       },
    \       'completion': {
    \           'autoimport': { 'enable': v:true },
    \           'callable': { 'snippets': 'add_parentheses' },
    \           'fullFunctionSignatures': { 'enable': v:true },
    \           'snippets': { 'custom': {} },
    \           'postfix': { 'enable': v:false },
    \           'termSearch': { 'enable': v:true, 'fuel': 10000 }
    \       }
    \   }
    \ })

I turned on the logs of the LSP server and compared the answers from the old version of Rust-Aanalyzer 1.84.1 and the new version 1.85.1.

In the answers from the new version of Rust-Aanalyzer there is no parameter additionaltextedits, but in the old version there is.

I tried rust-analyzer 1.85.1 with neovim + rust-analyzer plugin. Autoimport doesn't work in it either.

I also encountered this problem with vim9.1.1291 + rust1.85 + rust-analyzer(2025-05-26 v0.3.2474)

May be it`s not a bug. Try add follows into vimrc

function! s:RustCapabilities(server_info) abort
  let caps = lsp#default_get_supported_capabilities(a:server_info)
  if get(a:server_info, 'name', '') ==# 'rust-analyzer'
    let caps.textDocument.completion.completionItem.resolveSupport = {
          \ 'properties': ['additionalTextEdits', 'tags', 'labelDetails',
          \                'detail', 'documentation', 'filterText',
          \                'textEdit', 'command']
          \ }
    return caps
  endif
endfunction
let g:lsp_get_supported_capabilities = [function('s:RustCapabilities')]

Thanks for your reply!

I added this in my .vimrc but it did not help. vim-lsp autoimport does not work.
My version of vim and rust-analyzer:

vim 9.1.1497-1
rust-analyzer 1.88.0 (6b00bc3 2025-06-23)

I also checked whether the value additionalTextEdits exists in lsp#default_get_supported_capabilities({}) - yes it exists

I'm not sure why it doesn't work.

My vim version is vim9.1.1291, and the rust-analyzer is rust-analyzer 0.3.2519-standalone, whice is not part of rust installed.
The follow is all my vim-lsp settings:

let g:rust_analyzer_path = '/usr/local/bin/rust-analyzer'
let g:lsp_settings = {
\  'rust-analyzer': {
\    'cmd': [g:rust_analyzer_path],
\    'initialization_options': {
\      'cargo': {
\        'loadOutDirsFromCheck': v:true,
\        'autoreload': v:true,
\        'buildScripts': {
\           'enable': v:true,
\        },
\      },
\      'completion': { 'autoimport': {'enable': v:true} },
\      'procMacro': {
\        'enable': v:true,
\      },
\    },
\  },
\}
function! s:RustCapabilities(server_info) abort
  let caps = lsp#default_get_supported_capabilities(a:server_info)
  if get(a:server_info, 'name', '') ==# 'rust-analyzer'
    let caps.textDocument.completion.completionItem.resolveSupport = {
          \ 'properties': ['additionalTextEdits', 'tags', 'labelDetails', 'detail', 'documentation', 'filterText','textEdit', 'command']
          \ }
    return caps
  endif
endfunction
let g:lsp_get_supported_capabilities = [function('s:RustCapabilities')]
let g:lsp_fold_enabled = 0
let g:lsp_diagnostics_enabled = 0
let g:lsp_diagnostics_signs_enabled = 0
let g:lsp_document_highlight_enabled = 1
let g:lsp_document_code_action_signs_enabled = 0
let g:lsp_log_verbose = 1
let g:lsp_log_file = '/var/log/vim-lsp.log'
let g:lsp_show_message_log_level = 'log'

With the above settings, when i open rust file with vim, the rust-analyzer info like follows

And the log of vim-lsp like follows:

When i typing let a = Arc, vim like follows:

PS: The reason of the problem is not whether additionalTextEdits exists in capabilities, according to the code https://github.com/rust-lang/rust-analyzer/blob/master/crates/ide-completion/src/lib.rs#L40, what actually works is 'tags', 'labelDetails', 'detail', 'documentation', 'filterText','textEdit', 'command'

Thank you @luoyancn !

You were right! Now it works!

I added your settings in .vimrc again and checked variable g:lsp_get_supported_capabilities.
There was a different value in it because the plugin hrsh7th/vim-vsnip-integ redefined it.

~/.vim/plugged/vim-vsnip-integ/autoload/vsnip_integ/integration/vimlsp.vim:6:  let g:lsp_get_supported_capabilities =
 [function('s:get_supported_capabilities')]

When I turned off plugin hrsh7th/vim-vsnip-integautoimport began to work.
