Describe the feature

After yesterdays somewhat broken release of rust-analyzer (rust-lang/rust-analyzer#18854), which has now been fixed, it highlighted a maybe missing feature. Which would be to manually downgrade rust-analyzer version and perhaps even a toggle for auto-updating it, notification regarding rust-analyzer releases and updates?

Temporary workaround for the issue in question was to downgrade rust-analyzer, however with Zed it simply wasn't possible (at least not that we're aware of?).

•  Ability to downgrade rust-analyzer version
• Ability to toggle auto-updates for rust-analyzer
• rust-analyzer update notifications (if auto-update is not toggled on).

Thank you.

You could configure rust-analyzer to use a binary on your machine, for example.

{
  "lsp": {
    "rust-analyzer": {
      "binary": {
        "ignore_system_version": false,
      }
    }
  }
}

That would try to find rust-analyzer in $PATH.

Or you specify the path manually:

{
  "lsp": {
    "rust-analyzer": {
      "binary": {
        "path": "/Users/foobar/bin/rust-analyzer,
      }
    }
  }
}

I think that's a simpler workaround here than providing version management/selection in side Zed.
