I've noticed that there are various suggestions that rust-analyzer seems
to filter out, even if they make sense.
Here's an example of where it seems like there should be a suggestion,
but there isn't:
![https://i.imgur.com/wsjM6iz.png](https://i.imgur.com/wsjM6iz.png)
It turns out that this specific suggestion is not considered
`MachineApplicable`, which are the only suggestions that rust-analyzer
accepts. However if you read the documentation for `MachineApplicable`,
b3897e3d13/compiler/rustc_lint_defs/src/lib.rs (L27-L29)
then you realize that these are specifically only those suggestions that
rust-analyzer could even automatically apply (in some distant future,
behind some setting or so). Other suggestions that may have some
semantic impact do not use `MachineApplicable`. So all other suggestions
are still intended to be suggested to the user, just not automatically
applied without the user being consulted.
b3897e3d13/compiler/rustc_lint_defs/src/lib.rs (L22-L24)
So with that in mind, rust-analyzer should almost definitely not filter
out `MaybeIncorrect` (which honestly is named horribly, it just means
that it's a semantic change, not just a syntactical one).
Then there's `HasPlaceholders` which basically is just another semantic
one, but with placeholders. The user will have to make some adjustments,
but the suggestion still is perfectly valid. rust-analyzer could
probably detect those placeholders and put proper "tab through" markers
there for the IDE, but that's not necessary for now.
Then the last one is `Unspecified` which is so unknown that I don't even
know how to judge it, meaning that the suggestion should probably also
just be suggested to the user and then they can decide.
So with all that in mind, I'm proposing to get rid of the check for
Applicability entirely.
7457: Add no-buffering file logging and wait for a debugger option. r=vsrs a=vsrs
Adds two command line flags: `--no-buffering` and `--wait-dbg`.
Not sure if someone else needs this, but personally I found both flags extremely useful trying to figure out why RA does not work with Visual Studio. Or better to say why Visual Studio does not work with RA.

7353: Add LifetimeParam and ConstParam to CompletionItemKind r=matklad a=Veykril
Adds `LifetimeParam` and `ConstParam` to `CompletionItemKind` and maps them both to `TypeParam` in the protocol conversion as there are no equivalents, so nothing really changes there.
`ConstParam` could be mapped to `Const` I guess but I'm split on whether that would be better?
Additions were solely inspired by (the single) test output for const params.
Also sorts the variants of `CompletionItemKind` and its to_proto match.

I've noticed a bunch of "main loop too long" warnings in console when
typing in Cargo.toml. Profiling showed that the culprit is `rustc
--print cfg` call.
I moved it to the background project loading phase, where it belongs.
This highlighted a problem: we generally use single `cfg`, while it
really should be per crate.

7218: Fix typos r=Veykril a=regexident
Apart from the very last commit on this PR (which fixes a public type's name) all changes are non-breaking.

After we started reporting progress when running cargo check during
loading, it is possible to crash the client with two identical progress
tokens.
This points to a deeper issue: we might be running several cargo checks
concurrently, which doesn't make sense.
This commit linearizes all workspace fetches, making sure no updates are
lost.
As an additional touch, it also normalizes progress & result reporting,
to make sure they stand in sync.
This leaks a lot of LSP details into ide layer, which we want to avoid:
c9cec381bc/docs/dev (lsp-independence)
Additionally, all what this infra does is providing a toggle for
auto-import completion, but we already have one!
Rather than eagerly converting JSON, we losslessly keep it as is, and
change the shape of user-submitted data at the last moment.
This also allows us to remove a bunch of wrong Defaults
