What went wrong

With ALE completion enabled, when editing a .rs file, and starting to type the a few letters, all of the options are just things I've already typed in the file. So nothing that I haven't typed before is shown as an option for completion.

Reproducing the bug

  1. Enable ALE completion
  2. Open a .rs file
  3. Start typing

:ALEInfo

 Current Filetype: rust
Available Linters: ['analyzer', 'cargo', 'rls', 'rustc']
  Enabled Linters: ['cargo', 'rls']
  Ignored Linters: []
 Suggested Fixers: 
  'remove_trailing_lines' - Remove all blank lines at the end of a file.
  'rustfmt' - Fix Rust files with Rustfmt.
  'trim_whitespace' - Remove all trailing whitespace characters at the end of every line.

The only linter that works with completion is RLS, but the linting doesn't work on that one. I'm trying to get rust-analyzer to work, where completion doesn't work, but linting does.

This seems to be a rls specific issue. That language server has been deprecated and sunset. With it rls no longer available nor working, can we suggest this ticket to be closed?

I'll close this, and also mention that setting g:ale_completion_autoimport to 1 will probably solve the issue for any language server that lets you auto-import names.
